本発明は、液晶表示素子の製造方法に係り、特に接続電
極部の保護膜の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for manufacturing a liquid crystal display element, and particularly to a method for manufacturing a protective film for a connection electrode portion.
一般に液晶表示素子は、第２図に示したように透明電極
４及び配向膜７の付いた２枚の電極基板１．２を電極形
成面を対向させて、周辺部をシール材６で貼り合わせ液
晶セルを構成している。そして、液晶セルの周辺部の接
続電極部５から電気信号を導入する事により駆動してい
る。このように゛構成された液晶表示素子において、表
示する画素数が多くなるにつれ接続電極の本数が増加し
、各々の電極間隔が数十ミクロンから数ミクロンの細い
パターンとなる。このような電極間隔が狭い液晶表示素
子では、高湿中で駆動する時に隣接した電極間に電位差
の大きな信号が印加されると、特に透明電極として酸化
インジウムを用いたものでは、電気分解が生じ透明電極
の断線を起こす。In general, a liquid crystal display element is manufactured by placing two electrode substrates 1.2 with transparent electrodes 4 and alignment films 7 on them, with the electrode forming surfaces facing each other, and bonding the peripheral parts together with a sealant 6, as shown in FIG. It constitutes a liquid crystal cell. The liquid crystal cell is driven by introducing an electric signal from the connection electrode section 5 at the periphery of the liquid crystal cell. In a liquid crystal display element configured in this manner, as the number of pixels to be displayed increases, the number of connection electrodes increases, resulting in a thin pattern with an interval between each electrode of several tens of microns to several microns. When a liquid crystal display element with such narrow electrode spacing is driven in high humidity and a signal with a large potential difference is applied between adjacent electrodes, electrolysis may occur, especially in those using indium oxide as transparent electrodes. This causes disconnection of the transparent electrode.
これを防止するため一般には第２図のように、接続電極
部５に防湿用の保護膜６１を筆塗りするが、この方法で
は電極間隔の狭い細密パターン上に精度良く選択塗布す
る事は難しく、また均一な厚さにできないため、厚い部
分ではクラックや剥離が生じ十分な防湿効果が得られな
い。To prevent this, generally a moisture-proof protective film 61 is applied with a brush to the connecting electrode portion 5 as shown in Fig. 2, but with this method, it is difficult to selectively apply with precision on a fine pattern with narrow electrode spacing. Also, since the thickness cannot be made uniform, cracks and peeling occur in thick parts, making it impossible to obtain a sufficient moisture-proofing effect.
また、第３図のよ５に電極基板１．２に配向膜７を形成
した後、接続電極部５にスクリーン印刷法やフレキソ印
刷法等により、絶縁性の保護膜６２を選択的に精度良く
形成する方法もあるが、これを行う工程や材料費のため
コストアップとなっていた。Further, after forming the alignment film 7 on the electrode substrate 1.2 as shown in FIG. There is also a method of forming it, but this increases the cost due to the process and material costs.
本発明は、配向膜形成時に同時に接続電極部にも同一材
料で保護膜を形成する事を要旨とし、安価な方法で信頼
性を向上させた液晶表示素子を実現するための製造方法
を提供する事を目的としている。The present invention provides a manufacturing method for realizing a liquid crystal display element with improved reliability using an inexpensive method, in which a protective film is formed using the same material on the connection electrode portion at the same time as the alignment film is formed. It is aimed at something.
以下に、本発明を実施例により具体的に説明する。第１
図の電極基板１．２は透明導電膜を所望の電極パターン
にエツチングした後、フレキソ印刷等により液晶表示部
に配向膜７を形成するが、この時、液晶表示部外の接続
電極部５にも配向膜７と同時に保護膜６３も形成できる
ようなフレキソ版等を用意し、表示部の配向膜７と接続
電極部５、保護膜６３を、配向膜７と同一の材料で形成
する。The present invention will be specifically explained below using examples. 1st
In the electrode substrate 1.2 shown in the figure, after etching a transparent conductive film into a desired electrode pattern, an alignment film 7 is formed on the liquid crystal display area by flexographic printing or the like. A flexo printing plate or the like is prepared which can form the protective film 63 at the same time as the alignment film 7, and the alignment film 7 of the display section, the connection electrode section 5, and the protection film 63 are formed of the same material as the alignment film 7.
この方法によれば、保護膜６３は配向膜７と同時に形成
されるため、独立して行なっていた保護膜形成の工程を
無くす事ができる。また、配向膜７の選択により耐湿度
に対する信頼性を低下させる事はない。According to this method, since the protective film 63 is formed at the same time as the alignment film 7, it is possible to eliminate the step of forming the protective film, which was performed independently. Furthermore, the selection of the alignment film 7 does not reduce the reliability with respect to humidity resistance.
以上説明したように本発明による液晶表示素子の製造方
法によれば、接続電極部の精度の良い選択的な保護膜形
成が安価に行う事ができる。As explained above, according to the method for manufacturing a liquid crystal display element according to the present invention, selective formation of a protective film on the connection electrode portion can be performed with high precision and at low cost.
