Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は液晶表示装置の液晶の注入部形状に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to the shape of a liquid crystal injection part of a liquid crystal display device.
従来は、液晶表示装置の注入部の形状は第３図（ａ）、

を封止する時に封止剤をセル内に流入しないようにシー
ル剤１２と同様の材料で形成された注入部の壁１４から
成る形状が知られていた。Conventionally, the shape of the injection part of a liquid crystal display device is as shown in FIG. 3(a).
As shown in (b), a wall 14 of the injection part is formed of the same material as the sealant 12 to prevent the sealant from flowing into the cell when sealing the injection port 13 or the injection port 13 and the liquid crystal. A shape consisting of is known.
しかし、前述の従来技術では液晶の流入方向が一定でな
い為、特に大容量液晶表示装置の場合、注入品付近に液
晶の流入方向のちがいによる配向むらや配向不良が発生
し、表示品位が低下するという欠点を有していた。However, in the above-mentioned conventional technology, since the direction of inflow of liquid crystal is not constant, especially in the case of large-capacity liquid crystal display devices, alignment unevenness or alignment defects occur near the injected product due to the difference in the direction of inflow of liquid crystal, resulting in a decrease in display quality. It had the following drawback.
そこで本発明は上記欠点を解決するものであり、その目
的とするところは配向不良のない表示品位の高い液晶表
示装置を提供するところにある。SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned drawbacks, and its object is to provide a liquid crystal display device with high display quality and no alignment defects.

入部の形状が、液晶の液晶セル内での流入方向がほぼ一
定方向となるように形成したことを特徴とする。In the liquid crystal display device of the present invention, a liquid crystal cell is formed by bonding a pair of substrates having transparent electrodes on their inner surfaces with a sealant with a predetermined gap between them, and liquid crystal is injected into the gap from an injection port provided in the sealant. The liquid crystal display device is characterized in that the shape of the injection portion is formed such that the direction of inflow of liquid crystal into the liquid crystal cell is approximately constant.

表示装置が得られた。[Example] Example 1 As shown in the plan view of the liquid crystal display device in FIG. 4 was formed. Next, when the liquid crystal 5 was injected into the predetermined gap created by the sealant 2 by the vacuum injection method, the liquid crystal 5 was injected parallel to the side of the injection part as shown in FIG. 1(b). Next, after the predetermined gap is completely filled with liquid crystal, the injection port is sealed with epoxy adhesive to form a liquid crystal display device. As a result, there is no alignment unevenness or alignment defects near the injection port, and high quality is achieved. A liquid crystal display device was obtained.
実施例２
第２図の液晶表示装置の平面図に示すように液晶表示装

施例１と同様の効果が得られた。Example 2 As shown in the plan view of the liquid crystal display device in FIG. 2, the injection portion of the liquid crystal display device was formed from a large number of injection ports 3. When a liquid crystal display device was constructed by injecting liquid crystal in the same manner as in Example 1, the same effects as in Example 1 were obtained.

明らかである。In the present invention, the shape of the injection part as described above is used, but the present invention is not limited to this, and is also effective with any shape of the injection part so long as the inflow direction of the liquid crystal is in a substantially constant direction. . It goes without saying that the wall portion 4 may be formed at the same time as the sealant 2 is formed, or may be formed in separate steps.

位の高い液晶表示装置を提供できた。[Effects of the Invention] Hereinafter, I: As stated above, according to the present invention, by providing an injection part shape such that the inflow direction of liquid crystal is approximately constant, occurrence of poor alignment or uneven alignment near the injection port can be prevented. We were able to provide a liquid crystal display device with high display quality.
