Description of the Invention: [Technical Field] The present invention relates to a light-emitting element and a display, and more particularly to an organic electroluminescent device and an organic electro-luminescence display (OELD) . [Prior Art] The communication interface between the aborigines and the congratulations is currently based on the development of flat-panel displays. Among them, organic electroluminescent display has great application potential due to its self-illumination, non-viewing dependence, power saving, simple process, low cost, low temperature operation, high response speed and full color. Become the mainstream of the next generation of flat panel displays. Since the life cycle of the organic light-emitting materials of various color lights is inconsistent, the degree of attenuation of the red, green, and blue organic light-emitting materials will be different after using the organic electroluminescent display for a period of time, resulting in uneven display color. Disadvantages, so there are still many limitations in commercial applications. For this reason, some people have developed an organic electroluminescent display that combines an organic electroluminescent device with a color filter film. FIG. 1 shows a conventional organic electro-excitation. A partial cross-sectional view of a light display. Conventional organic electroluminescent display devices are mainly composed of a plurality of arrays of money-excited excitation elements, and only one electromechanical, luminescent display element is shown in the figure. The partial organic electroluminescent light shown in Figure i is shown as °. The main structure includes a substrate 11A, an anode layer 120, an organic light-emitting layer 13A, a cathode layer M0, and a color filter substrate 15A. The center, 120, the organic light-emitting layer 130 and the cathode layer 140 are sequentially disposed on the substrate, and the organic light-emitting layer 130 is adapted to emit white light. In addition, the color I2808Mtwf.doc/r filter substrate 150 is composed of two glass substrates 152 and a red light filter film R1〇, a green light filter film G1〇 and a blue light filter sealed between the two glass substrates 152. The film B10 is composed of. In the organic electroluminescent display using the above design, since the organic light-emitting layer 130 suitable for emitting white light is fully used, the red light filter film R10, the green light filter film G10 and the blue light filter film B10 are used for full color. Display, therefore, can solve the problem of different attenuation speeds of different kinds of organic light-emitting layers. However, since white light has different transmittances for the red light filter film R1 〇, the green light filter film Gi 〇 and the blue light filter film B10, there is also a problem that the color uniformity of the display screen is not good. SUMMARY OF THE INVENTION An object of the present invention is to provide an organic electroluminescent device which is suitable for increasing the luminous intensity of a specific wavelength. It is suitable for improving the color uniformity of the display. Another object of the present invention is to provide an organic electric excitation light

在更一實施例之上述有機電激發光顧示器中,不完全 透明層例如是布拉格反射層或金屬層。 政,在又另一實施例之上述有機電激發光顯示器中,有機 夯光層例如是白光有機發光層。 综上崎,在本發明之有機電紐光元件財機電激 ^顯示器中,由於每個有機電激發光元件中具有兩種以 2同厚度的填充層’因此可產生兩種以上的共振腔,進 ,提升特枝長的發光強度。此外,在搭配彩色濾光膜後 遇可依不_色濾光膜之特性而調整共振腔長度,以提升 9 1280S^^twf.doc/r 用,而材質則以例如銦錫氧化物等透明導電材質為佳。In the above organic electroluminescence detector of a further embodiment, the incomplete transparent layer is, for example, a Bragg reflection layer or a metal layer. In another embodiment of the above organic electroluminescent display, the organic phosphor layer is, for example, a white organic light-emitting layer. In the organic electroluminescence device of the present invention, since there are two kinds of filling layers of the same thickness in each organic electroluminescent device, two or more resonant cavities can be generated. Advance, increase the luminous intensity of the special branch length.

Conductive materials are preferred.

另外,透明填充層252與254是分別配置於第二透明 電極層240上的不同位置,且透明填充層254之厚度大於 透明填充層252之厚度。舉例而言’透明填充層252盘254 之材質可為二氧切卿2)、氮切(SiNx)等氧化物或氮化 物,亦或是其他適當的透明材質。不完全透明層27〇則是 覆蓋透明填充層252與254,而分別位於透明填充層252 與254上的不完全透明層27〇可彼此相連或分開。^完全 透明層270可為半透光的金屬層(例如銀、鋁),或是單對 或多對之布拉格反射(Distributed Bragg Refleet% dbr) 層0In addition, the transparent filling layers 252 and 254 are disposed at different positions on the second transparent electrode layer 240, respectively, and the thickness of the transparent filling layer 254 is greater than the thickness of the transparent filling layer 252. For example, the material of the transparent filling layer 252 disk 254 may be an oxide or nitride such as dioxin 2), nitrogen cut (SiNx), or other suitable transparent material. The incompletely transparent layer 27 is covered by the transparent filling layers 252 and 254, and the incompletely transparent layers 27, respectively located on the transparent filling layers 252 and 254, may be connected or separated from each other. ^ Completely transparent layer 270 can be a semi-transmissive metal layer (e.g., silver, aluminum), or a single or multiple pairs of Bragg reflection (Distributed Bragg Refleet% dbr) layer 0

稭由上述設計,當透過第一電極層220與第二透明電 極層240施加電流於有機發光層23〇時,有機發光層 所發出之光線即可直接通過第二透明電極層24〇,或經由 第-電極層22G之反射後通過第二透明電極層·而向外 射出。同時,光線在通過第二透明電極層24〇後,會受到 Z完全透明層27〇之部分反射,而在不完全透明層“ο與 弟-電極層22G之間來回反射並產生共振。值得注奇的 是,由於透明填充層252與254兩者之厚度不同,因二在 有機電激發光元件2〇0时有^種共振轉,進而使光線 於共费:後會在兩種特定波段上增加其發光強度與純度。、 遍Γ由上述特徵,若在本實施例之有機電激發光元件 ,更分別配置一濾光膜292與一濾光膜294在透明 真充層252與254上方之不完全透明層27〇上,且控 制透明填充層252與254兩者之厚度來改變共振距二二 11 I2B08l76>twf.d〇c/r 可分別增強適於穿透濾光膜292與294之波段的光線強 度,進而提高穿透濾光膜292與294後所得之色光的光線 強度與純度。舉例而言,若濾光膜292與294分別為藍光 與黃光濾光膜,則因為穿透濾光膜292與294之光量增加 且純度提高,所以在混光後所得之白光的亮度與演色性 (color rendering property)都可獲得提升。 此外,有機電激發光元件200還可更包括一透明平坦 層280,其覆蓋不完全透明層270,而濾光膜292與294 _ 則是配置在透明平坦層280上。透明平坦層280不僅具有 平坦化的功能,還可發揮保護作用,避免外界水氣、氧氣 或其他污染源破壞有機電激發光元件2〇〇内部的結構。當 然,為了保護濾光膜292與294,有機電激發光元件2〇〇 也可配置一保護層(未繪示)來覆蓋透明平坦層28〇、濾光膜 ' 292與294,或配置一封蓋基板(未綠示)來覆蓋於透明平坦 層280、濾光膜292與294上方。 一According to the above design, when a current is applied to the organic light-emitting layer 23 through the first electrode layer 220 and the second transparent electrode layer 240, the light emitted by the organic light-emitting layer can directly pass through the second transparent electrode layer 24, or via The reflection of the first electrode layer 22G is then emitted outward through the second transparent electrode layer. At the same time, after passing through the second transparent electrode layer 24, the light is partially reflected by the Z completely transparent layer 27, and is reflected back and forth between the incompletely transparent layer "o" and the electrode layer 22G to generate resonance. Oddly, since the thicknesses of the transparent filling layers 252 and 254 are different, since the organic electroluminescent element 2 〇 0 has a resonance turn, the light is co-fed: then it will be on two specific bands. The illuminating intensity and purity are increased. According to the above features, in the organic electroluminescent device of the present embodiment, a filter film 292 and a filter film 294 are disposed above the transparent fused layers 252 and 254, respectively. Incompletely transparent layer 27, and controlling the thickness of both transparent filling layers 252 and 254 to change the resonance distance 22 2 I2B08l76 > twf.d〇c / r can enhance the penetration of the filter film 292 and 294 respectively The light intensity of the band further increases the light intensity and purity of the color light obtained after penetrating the filter films 292 and 294. For example, if the filter films 292 and 294 are blue and yellow light filter films, respectively, The amount of light of the filter films 292 and 294 is increased and the purity is improved Therefore, the brightness and color rendering property of the white light obtained after the light mixing can be improved. Further, the organic electroluminescent device 200 can further include a transparent flat layer 280 covering the incomplete transparent layer 270, and The filter films 292 and 294 _ are disposed on the transparent flat layer 280. The transparent flat layer 280 not only has a flattening function, but also plays a protective role to prevent the external moisture, oxygen or other pollution source from damaging the organic electroluminescent element 2 The internal structure of the crucible.
