本考案は液晶セル、特に高密度ドツトマトリク
ス駆動用液晶セルの電極構造に関する。[Detailed Description of the Invention] The present invention relates to an electrode structure of a liquid crystal cell, particularly a liquid crystal cell for driving a high-density dot matrix.

成されている。 1 and 2 are a sectional view and a partially enlarged plan view showing the structure of a typical conventional dot matrix cell. A liquid crystal cell is constructed by bonding the peripheries of substrates 1 and 2, each having an electrode 3 made of indium oxide or the like, with a sealing material 4 such as an epoxy resin adhesive, and filling the gap with liquid crystal 5. has been done.
近年、液晶表示装置の進歩、普及は目覚しいも

隙間を微細にして、電極３とその間に位置する液
晶５で構成される画素数及び画素密度を増大させ
る必要がある。 In recent years, the progress and spread of liquid crystal display devices has been remarkable, and the trend is toward displaying a wide variety of images, characters, and the like. For this purpose, it is necessary to make the width of the pattern of the electrodes 3 and the gap finer, thereby increasing the number of pixels and the pixel density composed of the electrodes 3 and the liquid crystal 5 located between them.
この様に、電極３のパターンの微細化によつ

３のパターンの微細化による電気抵抗値の増大を
防いでいる。 As described above, due to the miniaturization of the pattern of the electrode 3, the material for the electrode 3 is not limited to the conventional transparent conductive film 3a made of a thin film such as indium oxide.
A metal electrode 3b made of a thin film of chromium, nickel, gold, or the like is formed on the surface of the transparent conductive film 3a to prevent an increase in electrical resistance due to finer patterns of the electrode 3.

材４の下部にも金属電極３ｂが連続的に配置され

３ｂとシール材４の接着力は酸化インジウム３ａ
のそれと比較して弱い。 When the peripheral parts of the substrates 1 and 2 having the electrodes 3a and 3b structures are bonded together using a sealing material 4 such as an epoxy resin adhesive, conventionally, metal electrodes 3b are also attached under the sealing material 4. Since the metal electrodes 3b and the sealing material 4 are arranged continuously, the adhesion reliability is poor.
weak compared to that of
殊に金は他の材料に比較して化学的に安定であ
り、該表面に水酸基などが形成されにくく、シー
ル材４との結合力が極めて弱い。 In particular, gold is chemically stable compared to other materials, hydroxyl groups, etc. are difficult to form on its surface, and its bonding force with the sealing material 4 is extremely weak.
従つて、高湿度雰囲気等の使用条件下で、本構
造からなる液晶セルは極めて短時間でシールはが
れ、空気もれ等が生じてしまう欠点がある。 Therefore, under usage conditions such as a high humidity atmosphere, the liquid crystal cell having this structure has the disadvantage that the seal peels off in an extremely short period of time, causing air leakage and the like.
本考案の目的は、透明導電膜３ａの表面に更に
金属電極３ｂを有す構造からなる液晶セルのシー
ルの信頼性向上にある。 An object of the present invention is to improve the reliability of the seal of a liquid crystal cell having a structure in which a metal electrode 3b is further provided on the surface of a transparent conductive film 3a.
上記目的を達成するために本考案においては、
シール材５の下部に配置される金属電極３ｂの一
部を切り欠いておく。 In order to achieve the above purpose, in this invention,
A part of the metal electrode 3b arranged under the sealing material 5 is cut out.
以下、本考案の詳細を実施例と共に説明する。 Hereinafter, details of the present invention will be explained along with examples.

が配置してある。 FIG. 3 is a partially enlarged plan view showing an embodiment of the present invention, in which a transparent electrode 6a made of indium oxide is formed on the surface of the upper substrate 1 as a member of the electrode 6, and furthermore, a transparent electrode 6a made of indium oxide is formed on the surface of the upper substrate 1. The length of the lower surface of the sealing material 4 for adhesion to the lower substrate 2 is approximately 0.3
Metal electrode 6b made of gold except for a portion of about mm

ツチング法等で容易に形成できる。 Although not shown, the electrodes 6 on the lower substrate 2 are also arranged in the same manner as in FIG. The pattern of the metal electrode 6b can be easily formed by conventional means such as photoetching.

る。 As described above, according to this embodiment, the upper substrate 1 and the lower substrate 2
Since the sealing material 4 is bonded to the transparent electrode 6a and the glass that is the material of the substrates 1 and 2, avoiding the metal electrode 6b, the bonding reliability is extremely high, similar to a liquid crystal cell that does not have the metal electrode 6b. Excellent effects can be obtained.
また懸念される電極６の電気抵抗は極めて僅か
な増加にとどまり、表示への影響は無視できる。 Further, the electrical resistance of the electrode 6, which is a concern, increases only slightly, and the influence on the display can be ignored.
