The image display unit 130 includes a A light-source polarization plate 150, an image generation unit 160, and an emission-side polarization plate 170. A viewer 500 (which will be described in detail later) is resisted by FIG. The right side of the reflective layer 200 views a stereoscopic image displayed by the stereoscopic image display device 100. For the viewer 500, the light source 120 is disposed on the rearmost side of the stereoscopic image display device 1A. When the stereoscopic image display device 100 is used (hereinafter referred to as In order to "the stereoscopic image display device 100 is in use"), white non-polarized light is incident on the surface of all of the light source side polarizers 150. It is worth noting that this embodiment uses one light source as a light source. 120, but it can also be combined with a light source and a condensing lens. An example of a concentrating lens is a Philippine A light source side polarizer 150 is disposed between the image generating unit 160 and the light source 120 and has a transmission axis and an absorption axis perpendicular to the transmission axis. When the non-polarized light emitted from the light source 120 is incident on the light source side polarizer 150, the light source side polarizer 150 transmits the light of the polarization axis parallel to the transmission axis, and blocks the polarization axis parallel absorption axis of the 200912462 light, wherein the direction of the polarization axis is The historical vibration direction of an electric field in light. As shown by the arrow in Fig. 1, when the viewer 500 views the vertical display device (10), the direction of the transmission axis in the light source side polarizer 1% is a direction in which the horizontal direction is rotated 45 degrees toward the upper right. The shirt image generating unit 160 includes one or more right eye image generating areas 1^2 and one or more left eye image generating areas 丨64. As shown in Fig. 1, these right eye scene = image generation area 162 and these left eye image generation areas 164 are a plurality of units which are horizontally divided by the image generation unit 16 and are alternately arranged in the vertical direction.

It is to be noted that the right-eye image light penetrating the right-eye image generation region 162 and the left-eye image light penetrating the left-eye image generation region (6) are differentiated into linearly polarized light having a polarization axis of a specific direction. Among them, the polarization axes of these specific directions can be in the same direction. In the embodiment shown in Fig. i, the directions of the two polarization axes are in the same direction as the direction of the transmission axis of the subsequent light-emitting side polarizer 17A. For example, the image generating unit (10) is a liquid crystai display (LCD) in which a plurality of small molecules are arranged in two dimensions in the horizontal and vertical directions, and the liquid crystal is sealed on the alignment film ( Alignment film) between each molecule. In the liquid crystal display 200912462, each molecule is driven by electric power to switch between a state in which the direction of the polarization axis of the transmitted light is not changed and a state in the direction of the polarization axis of the light transmitted by the 90-degree deflection.

When the right-eye image light that penetrates the right-eye image generation region 162 and the left-eye image light that penetrates the left-eye image generation region 164 are incident on the light-emitting side polarizer 170, the light-emitting side polarizer 17 〇 transmits only the polarization axis parallel to The light of the transmission axis and the light whose polarization axis is parallel to the absorption axis. As shown by the arrow in Fig. ,, when the viewer 500 views the stereoscopic image display device 1 , the direction of the transmission axis in the light-emitting side polarizer 170 is the direction in which the horizontal direction is toward the upper left rotation. The retarder 180 includes one or more right-eye polarizing regions 181 and one or more polarizing regions 182. The position and size of the right-eye polarizing regions 181 and the left-eye polarizing regions 182 of the retardation film 18A correspond to the right-eye image generating regions 162 of the image generating unit 160 and the left-eye image generating regions 164 of FIG. The location and size. Based on the above, when the stereoscopic image display device is cut in use, the right-eye image light penetrating through the right-eye image generation region 162 is incident on the right-eye polarized region 181, and penetrates the left of the f-eye image generation region 164. The ocular image light is incident on these left-eye polarizing areas (8). One or more light shielding structures 19 are disposed on the surface of the retardation film (10) facing the image display unit 13G such that the respective light shielding structures are present in a boundary between the right-eye polarizing region 181 and the left-eye polarizing region i82. - the light-shielding structure 19() absorbs and blocks the image light incident on the right-eye polarizing region (8) of the retardation plate (10), wherein the image light is from a left eye that is incident on the retardation film (10) and is connected to the right-eye polarization region 181.

The right eye image light of the area 182 右 a right-eye polarized area 200912462 181. By the above method, the light shielding structure 19 is disposed in the boundary on the retardation film 18〇 to prevent the right eye image light and the left eye image light emitted by the stereoscopic image display device 10 from interfering with each other. The right-eye polarizing region 181 transmits the incident right-eye image light without deflecting the polarization axis of the right-eye image light. The left-eye polarizing region 182 deflects the polarization axis of the incident left-eye image light to a direction perpendicular to the polarization axis of the right-eye image light incident on the right-eye polarizing region 181. Based on the above, as indicated by the arrow in Fig. 1, the polarization axis of the right-eye image light penetrating the right-eye polarizing region 181 is perpendicular to the polarization axis of the left-eye image light penetrating the left-eye polarizing region 182. In the retardation film ι8 图 in Fig. i, each arrow is used to indicate a polarization axis of the polarized light penetrating the retardation plate 180. The right-eye polarizing region 181 is made of, for example, a material such as transparent glass or resin, and the left-eye polarizing region 182 is made, for example, using a half-wavelength retarder having a left-eye image with respect to incidence. The direction of the polarization axis of the light is at an optical axis of 45 degrees. In the embodiment of Fig. 1, the direction of the optical axis of the left-eye polarizing region 182 may be a horizontal direction or a vertical direction. The optical axis is one of a fast axis or a slow axis when light passes through the left-eye polarizing region 182. In addition to the use of the retardation film 180, the right-eye polarizing region 181 and the left-eye polarizing region 182 may also be formed using a half-wavelength retarder, respectively, so that the right-eye image light and the left-eye image light emitted therefrom have respectively Linearly polarized light of mutually perpendicular polarization axes. 2 is a schematic view of the stereoscopic image display device 1 in use. As shown in FIG. 2, when the stereoscopic image display device 1 is used to view the stereoscopic image, the viewer 500 can view the right-eye image light and the left image projected by the stereoscopic image display device 100 by wearing the polarized glasses 220. Eye image light. The polarized glasses 220 are provided with a right eye image transmission section 232 and a left eye image transmission section 234, wherein when the viewer 5 wears the polarized glasses 22, The stomach position of the right-eye image transmissive unit 232 corresponds to the right eye of the viewer 5〇〇12, 1212, and the left-eye image transmissive unit corresponds to the left eye 514 of the viewer 500. The image transmissive unit 234 is a polarizing lens that is fixed in the direction of the transmission axis and is not polarized: the polarized lens is fixed to the frame of the polarizing glasses 22, and the right eye is transmitted as a polarizer. The direction of the right-eye polarizing region 181 is the same direction and

至5μιη。其中，黏著層300的厚度是由延遲片180的右眼偏 光區域181與左眼偏光區域182的入射面開始算起的厚度。 當遮光結構190的厚度較小時，塗佈黏著層300的步驟中可 避免氣泡進入。 以下將說明一種立體影像顯示裝置100的製作方法。此 實施例中的一種立體影像顯示裝置100的製作方法包括一塗 佈步驟（applying process )、一除氣步驟（degassing process )、 —疊合步驟（laminating process )以及一貼合步驟（attaching process)，其中塗佈步驟包括將一樹脂塗佈於影像顯示單元 130，除氣步驟包括對樹脂除氣，疊合步驟包括疊合影像顯示 單元130與延遲片180，而貼合步驟則包括透過將樹脂硬化 以貼合影像顯示單元130與延遲片180。 圖4為一種進行塗佈步驟之前的影像顯示單元π〇的剖 視示意圖。圖4中的影像顯示單元130的影像生成單元160 包括光源側玻璃基板（light-source glass substrate) 142、一 發光側玻璃基板（emission-side glass substrate) 144 以及由 密封於入光側玻璃基板142與出光側玻璃基板144之間所形 成的右眼影像生成區域162與左眼影像生成區域164。一光 源侧偏光片150配置於入光側玻璃基板142與光源之間，以 及發光側偏光片170配置於出光側玻璃基板144的出光側。 圖5為用以說明塗佈步驟的剖視圖。在塗佈步驟中，一 樹脂被塗佈於影像顯示單元130中的發光側偏光片170的出 光側表面，以形成黏著層300。其中，樹脂至少被塗佈於影 14 200912462 像生成單元160的這些右眼影像生成區域162與這些左眼影 像生成區域164朝向延遲片18〇的這些右眼偏光區域ι81與 這些左眼偏光區域182的區域。除了上述處理方式之外，樹 脂亦可被塗佈於發光側偏光片17G的整個表面。塗佈樹脂的 方法包括鋼模塗佈（diec〇ater)及凹版塗佈（gravurec〇ater) 或其他方式。另外’影像顯示單元130可被置放於真空爐 (vacuum furnace)中，以在真空爐中的低壓狀態下塗佈樹 脂。基於上述’可對樹脂進行除氣以提高其透明度 (transparency)及黏著度（adhesiveness)。另外，亦可在塗 佈M J3a後透過對影像顯示單元13 0使用超音波（ultrasonic vibration)以對樹脂進行除氣。在塗佈步驟中，黏著層3〇〇 被硬化前的厚度可等於或小於遮光結構19〇的厚度，且其厚 度取決於這些遮光結構190之間的開口面積、遮光結構190 的厚度及其他條件來設計。 使用於塗佈步驟中的樹脂可以透過加熱或照射紫外光硬 化’且此樹脂可為一具有一官能基（functi〇nal gr〇Up)以及 一環氧基（epOXy group)的樹脂，其中環氧基的側鏈（side chain)包括—不飽和雙鍵（unsaturateddouble bond)。另外， 亦可使用包含熱硬化樹脂與紫外光硬化樹脂的混合樹脂。紫 外光硬化樹脂例如是聚氨醋丙婦酸醋（Urethane Acrylate, UA)或不飽和丙稀酸醋（unsaturated polyester acrylate)。熱 硬化樹脂例如是不飽和聚醋樹脂（unsaturated polyester resin, UPR)、本二酸二浠丙酯樹脂（diallyl phthalate resin, DAP) 或聚氨酯（urethane resin, PU)。在常溫（攝氏25°C )下，上 述樹脂的較佳黏度可介於5〇〇厘泊（centipoises, cps)至1000 厘泊之間。當黏度小於5〇〇厘泊時，所塗佈的樹脂可能會溢 出。相反地，當黏度大於1000厘泊時，所塗佈的樹脂會難以 流進這些遮光結構190之間，進而無法平整地塗佈樹脂。 15 200912462 圖6為用以說明置放步驟的剖視圖。在置放步驟中，配 置有這些遮光結構190的延遲片180的表面被置放並重疊於 配置有黏著層300的影像顯示單元130的表面上。樹脂是 透過將影像顯示單元130與被置放於影像顯示單元130上的 延遲片180置放於真空爐中，並透過減少真空爐的壓力來進 行除氣。在除氣步驟中，亦可透過對影像顯示單元130與延 遲片180使用超音波來對樹脂進行除氣。 值得注意的是，如圖6所示，延遲片180的右眼偏光區 域181與左眼偏光區域182是透過一玻璃基板183支撐。延 遲片180的玻璃基板183比影像顯示單元130的出光側玻璃 基板144更厚，且延遲片180的整個表面與影像顯示單元130 的整個表面彼此貼合，因此不僅可維持強度，且可降低出光 側玻璃基板144的厚度。基於上述，可縮短影像顯示單元130 的影像生成單元160及延遲片180的右眼偏光區域181與左 眼偏光區域182之間的距離，以增加視角。舉例來說，當玻 璃基板183的厚度為0.7mm時，出光側玻璃基板144的厚度 可小於或等於0.5mm。 圖7為用以說明疊合步驟的剖視圖。在疊合步驟中，進 行置放步驟後的影像顯示單元130與延遲片180以延遲片 180朝上的方向被置放於載板（placement plate ) 610上。接 著，透過滾動中的滾輪（roller) 600而對延遲片180的玻璃 基板183施壓，以將影像顯示單元130與延遲片180互相疊 合。透過此方法，可整平黏著層300的厚度，以增加影像顯 示單元130與延遲片180的平坦度與平行度。黏著層300在 疊合步驟後的較佳厚度為相同於這些遮光結構190的厚度。 在疊合步驟中，滾輪600可透過繞著對準於圖7中所示的這 些右眼影像生成區域162與這些左眼影像生成區域164的方 向轉動來進行疊合步驟。滾輪600亦可透過繞著垂直於圖7 16 200912462 中所示的這些右眼影像生成區域162與這些左眼影像生成區 域164的長軸方向（longitudinal direction)轉動來進行疊合 步驟。影像顯示單元130可在疊合步驟後對準延遲片180。 於此實施例中，透過在黏著層300中混入石夕膠填充物 (silica-type filler )作為間隙物（spacer)可更容易對準。值 得注意的是，塗佈步驟、置放步驟與疊合步驟可在真空爐中 的一低壓狀態下進行。基於上述，可更有效地進行除氣以提 高生產力。 圖8為用以說明貼合步驟的剖視圖。在貼合步驟中，紫 外光由延遲片180的上方照射疊合步驟後的黏著層3〇〇，以 硬化黏著層300中的樹脂。舉例來說，此實施例中的紫外光 的照度（illuminance )為180 mW/cm2，累積的光量 (accumulated light quantity)為 3000mJ/cm2,且其波長為 365nm。基於上述，紫外光會照射黏著層3〇〇中的樹脂，以 硬化位於這些遮光結構190與延遲片18〇之間的區域中的樹 脂。 另外，亦可使用加熱裝置（heater)或其他類似的裝置由 外部加熱黏著層300，以透過加熱來硬化整個黏著層3〇〇。基 於上述，在上述區域中未被紫外光照射到的樹脂亦會被硬 化，以進一步確保影像顯示單元丨3〇與延遲片丨的貼合。 值得注意的是，照射紫外光與透過一加熱裝置來加熱可同步 進行。 將上述已貼合的影像顯示單元13〇與延遲片18〇容納於 圖3中所示的箱體110中，即可完成立體影像顯示裝置1〇〇。 根據上述實施例，影像顯示單元13〇與延遲片18〇是透過塗 佈樹脂來互相貼合，其中樹脂至少被塗佈於影像生成單元 160的這些右眼影像生成區域162與這些左眼影像生成區域 17 200912462 164重疊於延遲片180的這些右眼偏光區域181與這些左眼 偏光區域182的的區域。基於上述，影像顯示單元130可與 延遲片180緊密地互相固定，藉以增加視角。 圖9為本發明一實施例的一種抗反射層200的示意圖。 上述的立體影像顯示裝置100包括一位於延遲片180與觀看 者500之間的抗反射層200。抗反射層200包括依序排列於 延遲片180的玻璃基板183上的一黏著層202、一基材（base material) 204、一石更化膜（hard coating) 206、一高折射率 (refractive index)樹脂208以及一低折射率樹脂210。黏著 層202的厚度例如是25μιη。另外，基材204例如是三醋酸纖 維素（tri-acetyl cellulose，TAC)膜，且其厚度為 80μιη。硬 化膜206的厚度例如是5μπι。高折射率樹脂208與低折射率 樹脂210的折射率分別為1.65與1.40,且其厚度皆為0.1 μηι。 圖10為根據本發明一實施例的製作方法所製作出的另 一種立體影像顯示裝置101的立體分解圖。圖10中的立體影 像顯示裝置101的結構與圖1中的立體影像顯示裝置100的 結構相同的部分以相同的標號來標示，且於此不再贅述。如 圖10所示，立體影像顯示裝置101包括一延遲片185，用以 取代立體影像顯示裝置100的延遲片180。此延遲片185包 括多個右眼偏光區域186以及多個左眼偏光區域187。其中， 這些右眼偏光區域186與這些左眼偏光區域187皆為1/4波 長延遲片，且其光軸互相垂直。在延遲片185中，這些右眼 偏光區域186與這些左眼偏光區域187的位置與大小對應於 這些右眼影像生成區域162與這些左眼影像生成區域164的 位置與大小（如同延遲片180的這些右眼偏光區域181與這 些左眼偏光區域182的位置與大小）。基於上述，立體影像顯 示裝置101在使用狀態下，穿透右眼影像生成區域162右眼 18 200912462 y像光會入射至這些右眼偏光區域186，而穿透左眼影像生 成區域164的左眼影像光會入射至這些左眼偏光區域187。 一多個遮光結構190被配置在延遲片185朝向影像顯示單 几130的一表面上，以使各遮光結構19〇存在於右眼偏光區 域186與左眼偏光區域187之間的一邊界中。一遮光結構190 吸收並阻隔朝向延遲片185的一右眼偏光區域186入射的影 像光j其中此影像光來自於應入射至延遲片185鄰接於右眼 偏光區域186❾一左眼偏光區域187的左眼影像光。另外，

For example, a polarizing lens, ^ (4) a transmissive unit 234, respectively, is attached to a film of a polarizing film, and the film is stretched by a single sleeve and penetrates the retarder # + ^ 182 right eye image light and 2: polarized light region 181 and left-eye polarized area device!. . To view the stereo:; === stereoscopic image display Polarized glasses 220 to view the vertical (four) derby viewer 500 can only see the right eye by wearing the above buckle; ^ H 丨 (8). Based on the above, the right eye is imaged. Therefore, while viewing, the left eye 514 can only be viewed as a left stereo image. The right eye image light and the left eye image light can be arranged in a housing 11 for a schematic view. As shown in Fig. 3, the outline of the stand-up shirt image display device 100 is selected. Furthermore, 4: the display unit 130 is indicated by an outer frame 165 on the light exit side of the unit 130. The reflective layer 200 is attached to the image display element 130. Among them, the retardation film Γ8: the case where the two-unit unit is good is sticky; the image is attached to the image display thickness of !9〇. Here, the thickness of the crucible is the same as the thickness of the light-shielding structure 3〇0, which is not only the same as the thickness of the adhesion layer 1冉υϋ, and the thickness of the adhesion layer 13 200912462 layer 300 can be closer to the thickness of the light-shielding structure 190. 1.5 times. For example, when the thickness of the light shielding structure 190 is from 1 μm to 15 μm, the thickness of the adhesive layer 300 is preferably from ΙΟμηη to 20 μm. Further, when the thickness of the light shielding structure 190 is 2 μm to 3 μm, the adhesive layer 300 preferably has a thickness of 2 μm to 5 μm. Here, the thickness of the adhesive layer 300 is the thickness of the right-eye polarizing region 181 of the retardation film 180 and the incident surface of the left-eye polarizing region 182. When the thickness of the light shielding structure 190 is small, air bubbles can be prevented from entering in the step of applying the adhesive layer 300. A method of fabricating the stereoscopic image display device 100 will be described below. A manufacturing method of a stereoscopic image display device 100 in this embodiment includes an applying process, a degassing process, a laminating process, and an attaching process. The coating step includes applying a resin to the image display unit 130, the degassing step includes degassing the resin, the laminating step includes superimposing the image display unit 130 and the retardation film 180, and the bonding step includes transmissing the resin The image is displayed to be bonded to the image display unit 130 and the retardation film 180. Fig. 4 is a schematic cross-sectional view showing the image display unit π 之前 before the coating step. The image generating unit 160 of the image display unit 130 in FIG. 4 includes a light-source glass substrate 142, an emission-side glass substrate 144, and a glass substrate 142 sealed by the light-incident side. The right eye image generation area 162 and the left eye image generation area 164 formed between the light exit side glass substrate 144 and the light exit side glass substrate 144. The light source side polarizer 150 is disposed between the light incident side glass substrate 142 and the light source, and the light emitting side polarizer 170 is disposed on the light exit side of the light exit side glass substrate 144. Fig. 5 is a cross-sectional view for explaining a coating step. In the coating step, a resin is applied to the light-emitting side surface of the light-emitting side polarizer 170 in the image display unit 130 to form the adhesive layer 300. The resin is applied at least to the right eye image generation region 162 of the image generation unit 160 and the right eye polarization region ι 81 of the left eye image generation region 164 toward the retardation film 18A and the left eye polarization region 182. Area. In addition to the above treatment, the resin may be applied to the entire surface of the light-emitting side polarizer 17G. The method of coating the resin includes die coating and gravure coating or other means. Further, the image display unit 130 may be placed in a vacuum furnace to coat the resin in a low pressure state in the vacuum furnace. The resin can be degassed based on the above to improve its transparency and adhesiveness. Alternatively, the resin may be degassed by applying ultrasonic vibration to the image display unit 130 after coating M J3a. In the coating step, the thickness of the adhesive layer 3 before being hardened may be equal to or smaller than the thickness of the light shielding structure 19, and the thickness thereof depends on the opening area between the light shielding structures 190, the thickness of the light shielding structure 190, and other conditions. To design. The resin used in the coating step may be cured by heating or irradiation with ultraviolet light' and the resin may be a resin having a functional group (functi〇nal gr〇Up) and an epoxy group (epOXy group), wherein the epoxy The side chain of the base includes an unsaturated double bond. Further, a mixed resin containing a thermosetting resin and an ultraviolet curing resin can also be used. The ultraviolet light curing resin is, for example, Urethane Acrylate (UA) or unsaturated acrylate (unsaturated polyester acrylate). The thermosetting resin is, for example, an unsaturated polyester resin (UPR), a diallyl phthalate resin (DAP) or a urethane resin (PU). The preferred viscosity of the above resin may be between 5 centipoises (cps) and 1000 centipoise at room temperature (25 ° C). When the viscosity is less than 5 〇〇 centistoke, the applied resin may overflow. On the contrary, when the viscosity is more than 1000 cps, the applied resin may hardly flow between the light-shielding structures 190, so that the resin may not be applied uniformly. 15 200912462 Figure 6 is a cross-sectional view for explaining the placement step. In the placing step, the surface of the retardation plate 180 on which the light shielding structures 190 are disposed is placed and superposed on the surface of the image display unit 130 on which the adhesive layer 300 is disposed. The resin is placed in a vacuum furnace by placing the image display unit 130 and the retardation film 180 placed on the image display unit 130, and degassing by reducing the pressure of the vacuum furnace. In the degassing step, the resin can also be degassed by using ultrasonic waves on the image display unit 130 and the delay sheet 180. It is to be noted that, as shown in FIG. 6, the right-eye polarizing region 181 and the left-eye polarizing region 182 of the retardation film 180 are supported by a glass substrate 183. The glass substrate 183 of the retardation film 180 is thicker than the light-emitting side glass substrate 144 of the image display unit 130, and the entire surface of the retardation film 180 and the entire surface of the image display unit 130 are attached to each other, thereby not only maintaining strength but also reducing light emission. The thickness of the side glass substrate 144. Based on the above, the distance between the right-eye polarizing region 181 of the image generating unit 160 of the image display unit 130 and the right-eye polarizing region 181 of the retarder 180 and the left-eye polarizing region 182 can be shortened to increase the angle of view. For example, when the thickness of the glass substrate 183 is 0.7 mm, the thickness of the light-emitting side glass substrate 144 may be less than or equal to 0.5 mm. Figure 7 is a cross-sectional view for explaining the lamination step. In the superimposing step, the image display unit 130 and the retardation film 180 after the placing step are placed on the placement plate 610 in the upward direction of the retardation plate 180. Then, the glass substrate 183 of the retardation film 180 is pressed by the roller 600 in the scroll to superimpose the image display unit 130 and the retardation film 180 on each other. By this method, the thickness of the adhesive layer 300 can be leveled to increase the flatness and parallelism of the image display unit 130 and the retardation film 180. The preferred thickness of the adhesive layer 300 after the lamination step is the same as the thickness of the light shielding structures 190. In the superimposing step, the roller 600 can perform the superimposing step by rotating in the directions of the right eye image generating regions 162 and the left eye image generating regions 164 aligned in Fig. 7 . The scroll wheel 600 can also be superimposed by rotating in the longitudinal direction of the right eye image generation region 162 and the left eye image generation region 164 perpendicular to that shown in Figures 7 16 200912462. The image display unit 130 can align the retarder 180 after the folding step. In this embodiment, it is easier to align by incorporating a silica-type filler as a spacer in the adhesive layer 300. It is to be noted that the coating step, the placing step and the laminating step can be carried out in a low pressure state in the vacuum furnace. Based on the above, degassing can be performed more efficiently to increase productivity. Fig. 8 is a cross-sectional view for explaining a bonding step. In the bonding step, the ultraviolet light is irradiated from the upper side of the retardation film 180 to the adhesive layer 3A after the lamination step to harden the resin in the adhesive layer 300. For example, the ultraviolet light in this embodiment has an illuminance of 180 mW/cm2, an accumulated light quantity of 3000 mJ/cm2, and a wavelength of 365 nm. Based on the above, the ultraviolet light illuminates the resin in the adhesive layer 3 to harden the resin in the region between the light-shielding structure 190 and the retardation film 18A. Alternatively, the adhesive layer 300 may be externally heated using a heater or the like to harden the entire adhesive layer 3 by heat. Based on the above, the resin which is not irradiated with ultraviolet light in the above region is also hardened to further ensure the adhesion of the image display unit 丨3〇 to the retardation sheet. It is worth noting that the irradiation of ultraviolet light and the heating through a heating device can be performed simultaneously. The above-described image display unit 13A and the retardation film 18 are accommodated in the casing 110 shown in Fig. 3, whereby the stereoscopic image display device 1 can be completed. According to the above embodiment, the image display unit 13 and the retardation film 18 are bonded to each other through a coating resin, wherein the resin is applied to at least the right eye image generation region 162 of the image generation unit 160 and the left eye image generation. The region 17 200912462 164 is superimposed on the regions of the right-eye polarizing region 181 of the retardation film 180 and the left-eye polarizing regions 182. Based on the above, the image display unit 130 can be closely fixed to the retarder 180 to increase the angle of view. FIG. 9 is a schematic diagram of an anti-reflection layer 200 according to an embodiment of the invention. The above-described stereoscopic image display device 100 includes an anti-reflection layer 200 between the retardation film 180 and the viewer 500. The anti-reflective layer 200 includes an adhesive layer 202 sequentially arranged on the glass substrate 183 of the retarder 180, a base material 204, a hard coating 206, and a high refractive index. Resin 208 and a low refractive index resin 210. The thickness of the adhesive layer 202 is, for example, 25 μm. Further, the substrate 204 is, for example, a tri-acetyl cellulose (TAC) film and has a thickness of 80 μm. The thickness of the hardened film 206 is, for example, 5 μm. The high refractive index resin 208 and the low refractive index resin 210 have refractive indices of 1.65 and 1.40, respectively, and have a thickness of 0.1 μm. FIG. 10 is an exploded perspective view of another stereoscopic image display device 101 produced by a manufacturing method according to an embodiment of the invention. The same components of the configuration of the stereoscopic image display device 101 in FIG. 10 and those of the stereoscopic image display device 100 of FIG. 1 are denoted by the same reference numerals and will not be described again. As shown in FIG. 10, the stereoscopic image display device 101 includes a retardation film 185 for replacing the retardation film 180 of the stereoscopic image display device 100. This retarder 185 includes a plurality of right-eye polarizing regions 186 and a plurality of left-eye polarizing regions 187. The right-eye polarizing region 186 and the left-eye polarizing regions 187 are both 1/4-wavelength retarders, and their optical axes are perpendicular to each other. In the retardation film 185, the positions and sizes of the right-eye polarized regions 186 and the left-eye polarized regions 187 correspond to the positions and sizes of the right-eye image generating regions 162 and the left-eye image generating regions 164 (like the retarder 180). These right-eye polarizing regions 181 and the positions and sizes of these left-eye polarizing regions 182). Based on the above, the stereoscopic image display device 101 penetrates the right eye image generation region 162 in the use state, and the right eye 18 200912462 y image light is incident on the right eye polarization region 186 and penetrates the left eye of the left eye image generation region 164. Image light is incident on these left-eye polarizing regions 187. A plurality of light shielding structures 190 are disposed on a surface of the retardation film 185 facing the image display unit 130 such that the light shielding structures 19 are present in a boundary between the right-eye polarizing region 186 and the left-eye polarizing region 187. A light shielding structure 190 absorbs and blocks image light j incident toward a right-eye polarizing region 186 of the retardation plate 185, wherein the image light is incident from the left side of the left-eye polarizing region 187 adjacent to the right-eye polarizing region 186. Eye image light. Further, the light-shielding structure 190 « and blocks the cardiographic light incident toward the left-eye polarizing region of the retardation plate 185, wherein the image light is from the right-eye mercerizing light which should be incident on the retardation plate 185 adjacent to the left-eye polarizing region 187. By the above method, the mask::: 190 is disposed in the boundary on the retarder 185 to prevent the right-eye image light and the left-eye image light emitted by the stereoscopic image display device 1〇1 from interfering with each other. The incident light emitted from the retardation plate 185 is circularly polarized light whose opposite directions of rotation of the polarization axis are opposite to each other. For example, the incident light emitted by the right-eye polarizing region 186 is a circularly polarized light in a clockwise direction, and the incident light emitted by the left-eye polarizing region 187 is a counter-clockwise circularly polarized light. It is to be noted that each of the retarders 185 in the ® H) indicates the direction of rotation of the polarized light that has passed through the retardation plate 185. For example, the right-eye polarizing regions 186 may be 1/4-wavelength retarders whose optical axes are horizontal, and the left-eye polarizing regions 187 may be 1/4-wave retarders whose optical axes are perpendicular. As in the embodiment of the stereoscopic image display device 100, in the stereoscopic image display device 1A shown in Fig. 1A, the adhesive layer 3 is used to attach the retarder 185 to the image generating unit (10). Based on the above, the image display unit 13 can be closely fixed to the retarder 185 to increase the angle of view. 19 200912462 When viewing the delay chip set 101 as shown in FIG. 1, the stereoscopic image of the viewer 500 wearing a polarization limit 185 is displayed at the position of the right eye 512 and corresponds to the left eye 51|brother' Long retardation film and a polarizing lens. In the 1/4 wavelength retarder t glasses provided with the right eye 512 of the 1/4 wave in the above-mentioned partial positions, the 'horizontal light set for the left eye 514 of the viewer 500 for the viewer 500 The shaft, while the vertical optical axis. In addition, the viewer's 5 〇〇 wavelength retarder has a light lens and a bias angle set for the left eye 5 'right eye 512 of the viewer 500' is viewed from the direction of the viewer 500. The polarizing lens is used to view the stereoscopic image display device with polarized glasses in the direction of the "seven degrees 45 degrees" and the direction of the absorption axis is perpendicular to the direction of the transmission axis. For the right eye 512 of the viewer 500, when the direction of the depolarization station is clockwise circularly polarized light with respect to the viewer, the circularly polarized light is transmitted through the optical axis at a quarter wavelength delay in the horizontal direction. The sheet is converted to linearly polarized light at 45 degrees to the upper right and penetrates the polarizing lens to be seen by the right eye 512 of the viewer. For the left eye 514 of the viewer 500, when the direction of the polarization axis is incident on the polarized light in the counterclockwise direction with respect to the viewer 500, the circularly polarized light is transmitted through the 1/4 wavelength retarder in the vertical direction of the optical axis. It is a linearly polarized light of 45 degrees to the upper right and penetrates the polarizing lens and is seen by the left eye 514 of the viewer 5 inches. According to the above manner, by wearing the above-mentioned polarized glasses, it is said that the right-eye image display device 101' can only see the right-eye image light, and the left-eye 514 can only see the left-eye image light. Therefore, the viewer $〇〇 can recognize the right eye image light and the left eye image light as a litigation image. According to the above embodiment, the image display unit 13A and the retardation sheet 1 (or 185) are adhered to each other through a coating resin, wherein the tree wax is applied at least to the right eye image generation regions 62 of the image generation unit 160 and The left-eye image generating area 164 is overlapped with the right-eye polarizing area 181 (or 186) of the retarder 180 (or 185) and the area 20 200912462 of the left-eye polarizing area 182 (or 187).

Here, the width of the light-shielding structure 19 〇 22 200912462 was set so that the aperture ratio of Example 2 was the same as that of Comparative Example 1. In Embodiment 2, the aperture ratio is calculated in the same manner as the gate i. <Table 1> Comparative Example 1 - Example 1 Example 2 Light-emitting side glass substrate 144 0.7 0.3 0.3 Light-emitting side polarizer 170 0.18 0.18 0.18 Width of light-shielding structure 190 0.135 0.135 0.074 Θ1 (angle) 4.37 7.98 4.37 Θ2 (angle) 0.01 0.02 0.01 Viewing angle (angle) 4.38 8.00 4.38 Opening ratio (%) 49.9 49.9 72.7 It can be clearly seen from Table 1 that the viewing angle of the first embodiment is about 1.8 times that of the comparative example 1 (determined by dividing 8.01 by 4_39) . Further, the opening ratio of Example 2 was about 1.5 times the opening ratio of Comparative Example 1 (determined by dividing 72.7 by 49 9). In other words, the luminance of Embodiment 2 is about j 5 times the luminance of Embodiment 1. As described above, according to the above embodiment, the image display unit 13 and the retarder 180 (or 185) are bonded to each other through the coating resin, wherein the transmissive resin is applied to at least the right of the image generating unit 160. The eye image generation region 162 and the left eye image generation region 164 overlap the regions of the right eye polarization region 181 (or 186) of the retardation film 18 (or 185) and the left eye polarization region 182 (or 187). Based on the above, the image display unit 13 can be closely fixed to the retarder 180 (or 185) to increase the angle of view. Furthermore, compared with the other, between the image display unit 13A and the retardation film 18A (or 185), 23 200912462 in the case of an air iayer, internal reflection can be limited to the image. The display unit 130 is interposed between the retarder 180 (or 185) to thereby reduce interference. In particular, even when the large-size image display unit 130 is folded, the adhesive layer 300 and the retarder 180 (or 185) can be bent. Therefore, the image display unit 130 and the retarder 180 (or 185) can be avoided. A wavy line is created between them. Further, the resin is hardened after the laminating step, so that the adhesive layer 300 can have a uniform thickness to increase the flatness and parallelism of the image display unit 13A and the retardation plate 180 (or 185). Further, by shortening the distance between the image display unit 13A and the retardation film 18A (or 185), the width of each of the light shielding structures 190 can be narrowed while maintaining the same degree of viewing angle as before shortening the distance. Based on the above, an aperture portion between the light shielding structures 19A can be enlarged to increase the brightness of the screen. Figure 12 is a cross-sectional view for explaining an attaching step in a manufacturing method of another embodiment of the present invention. This fabrication method includes an attachment step that can be used to replace the coating step in the fabrication process illustrated in Figures 1-11. The manufacturing method further includes a heating step. In the manufacturing method, the parts of the manufacturing method which are the same as those of the manufacturing method shown in the figure are denoted by the same reference numerals and will not be described again. As shown in Fig. 12, the attaching step includes attaching an adhesive sheet 700 to a light incident side surface of the retardation film 18A. The adhesive sheet 7 〇〇 includes a resin layer 720 and a release film 71 用以 for the resin layer 72 支. The resin layer 720 is an ultraviolet curable resin, and is, for example, an acrylate resin such as Threebcmd (trademark) 163() produced by Nippon Sanken Co., Ltd. In the embodiment shown in Fig. 12, the adhesive sheet 7〇〇 a = the surface of the resin layer 720 of the adhesive sheet 700 is attached to the surface of the retardation sheet i8 〇 light distribution structure 190 to be attached to the retardation sheet 18A. The value of 彳曰, the main β of the film 700 can be the whole roll can be cut according to the demand of the adhesion: ',: Yes 】 First: Shape of the single piece of sticky tablets. Wherein the thickness of the resin layer 720 of the adhesive sheet 700 is 15 to 75 μm when the thickness of the light-shielding structure 190 is 3_1. Based on the above, the resin uniformly fills the concave portion between the light-shielding structures 190 to make the surface flat. Figure 13 is a cross-sectional view for explaining the attaching step of Figure 12 in succession. As shown in FIG. 13, the attaching step further includes pressing the side of the release film 710 of the adhesive sheet 700 attached to the light incident side surface of the retardation film 180 through a heating roller 800 to superimpose the adhesive sheet 700 on the delay. The steps of slice 180. In the step shown in FIG. 13, the attaching step is performed by rolling the heating roller 800 at a speed of 0.3 m/min along the arrow direction shown in the drawing on the resin layer 720 of the adhesive sheet 700 to advance The adhesive sheet 700 was attached to the retarder 180, wherein the temperature in the chamber was 80 ° C and the pressure was 0.1 MPa. By performing the above-described attaching step by using the heating roller 800, the resin layer 720 can conform to the concave/convex shape of the light-shielding structure 190, whereby the resin layer 720 can be filled with the light entering the retarder 180. The entire surface of the side. Figure 14 is a cross-sectional view for explaining the attaching step of Figure 13 in succession. As shown in Fig. 14, the attaching step further includes a step of removing the release film 710 of the adhesive sheet 700 from the resin layer 720. As a result, the resin layer 720 will remain on the retarder 180 and will be exposed. Fig. 15 is a cross-sectional view showing the placing step of placing the retardation film 180 on the image display unit 130, which is included in the above-described lamination step, and is continued after the above-described attaching step. As shown in Fig. 15, the resin layer 720 exposed in the step of Fig. 14 is superposed on the surface of the light-emitting side polarizer 170 of the image display unit 130. At this time, the alignment between the delay slice 180 and the image display unit 130 should be decided. When determining the alignment between the retardation film 180 and the image display unit 130, the retarder 180 may be removed from the image display unit 130 and stacked thereon several times. However, since the resin layer 720 has been overlapped with the retardation film 180, even if the retardation film 180 is removed from the image display unit 130 by 25 200912462, the resin layer 720 remains surely on the side of the retardation film 180, so that the retardation can be made. ; 1 180 is easily removed from the image display unit 130. After determining the alignment between the retardation film 180 and the image display unit 130, the image display unit 130 is superimposed on the retardation film 180 in a vacuum state. In the vacuum lamination step, the image display unit 130 and the retardation film 180 which are overlapped each other are placed in a vacuum furnace having a temperature of 80 ° C and a pressure of 150 Pa. Further, a balloon shape member is used to supply O.IMpa pressure to one of the image display unit 130 and the retardation film 180, and the above state is maintained for 3 minutes. As a result, the image display unit 130 is pressed to be attached to the delay sheet 180, and the air bubble in the resin layer 720 is also removed. A heating step is further included after the above lamination step. In this heating step, the image display unit 130 and the retarder 180 are heated at a pressure higher than one atmospheric pressure. The preferred gas pressure in this heating step is higher than the gas pressure in the lamination step. One of the embodiments of this heating step is to place the image display unit 130 and the retarder 180 under a chamber having a temperature of 60 ° C and a pressure of 〇.6 MPa for 1 hour. Based on the above, the deformation generated when the image display unit 130 and the retardation film 180 are subjected to the laminating step in a vacuum state is expected to be eliminated in this heating step. Further, after the vacuum lamination step, the bubbles remaining in the resin layer 720 which are not removed may be broken or extruded in this heating step. After this heating step, ultraviolet light is irradiated to conform to the light-shielding structure 190 and the retardation plate 180, just like the bonding step shown in FIG. In summary, in addition to the effects of the embodiment shown in Figures 1-11, the embodiment shown in Figures 12-15 can achieve the following effects. This embodiment uses an adhesive sheet 700 to conform the image display unit 130 and the retardation film 180 so that the retardation film 180 can be easily removed from the image display unit 130 before the resin layer 720 of the adhesive sheet 700 is hardened. Based on the above, it is easier to align the delay slice 180 with the image display 26 200912462 unit 130. In this embodiment, the resin layer 720 is superposed on the retarder 180 side through the heating roller 800 or the like. Therefore, when the retarder 180 is removed from the image display unit 130, the resin layer 720 is more reliably retained in the retarder. The 180 side allows the retarder 180 to be easily removed from the image display unit 130. In addition, by superposing the resin layer 720 on the retarder 180 in advance through the above-described laminating step, the resin layer 720 can conform to the concave/protruding shape of the light-shielding structures 190, so that the resin layer 720 can be surely covered with the retardation film. 180 is between the image display unit 130. In addition, the addition of a pressing process between the laminating step and the laminating step can eliminate the deformation of the image display unit 130 and the retarder 180 during the lamination step. In addition to this, the bubbles remaining in the resin layer 720 which are not removed after the vacuum lamination step may be broken or extruded in the heating step. It is noted that in the embodiment shown in Figures 12-15, the adhesive sheet 700 is previously attached to the retarder 180 prior to the step of laminating. However, the adhesive sheet 700 may be attached to the image display unit 130 in advance before the folding step. While a part of the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make a few changes without departing from the spirit and scope of the invention. The scope of protection of the present invention is therefore defined by the scope of the appended claims. 27 200912462 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a three-dimensional image display device 100 produced by a manufacturing method according to an embodiment of the present invention. 2 is a schematic view of the stereoscopic image display device 1 in use.
