で断線する。A conventional liquid crystal display element has a structure as shown in FIGS. 1 and 2. That is, two upper and lower substrates 1 and 2 on which transparent conductive electrodes are formed are placed facing each other, the periphery is sealed with a sealing material 3, and liquid crystal is sealed inside. By the way, since the upper and lower substrates 1 and 2 are opposed to each other with an interval of 8 to 10 μ-
A gap 4 of 8 to 10 μm is provided around the outer periphery of the element. Conventional displays for watches and calculators are used in places with relatively low humidity, but when used in industrial equipment, humidity can be quite high. When used in high humidity, moisture enters the gap 4, and this and impurities cause the external lead 5 to
When a potential difference is created between the two, 1.0. Migration occurs in the twisted lead 5 and the lead 5 is disconnected. 5
The wire will break within 24 hours at a temperature of 5°C and 95% humidity with a voltage difference of several volts between the leads.
本発明の目的は、上記欠点を取りのぞき、高信幀性の液
晶表示素子を提供することにある。An object of the present invention is to eliminate the above-mentioned drawbacks and provide a highly reliable liquid crystal display element.
以下、本発明の一実施例を第３図により説明する。なお

。An embodiment of the present invention will be described below with reference to FIG. Note that the same members or corresponding parts as in FIGS. 1 and 2 will be described with the same reference numerals. A gap 4 between the upper and lower substrates 1.2 is filled with urethane resin 6. How to fill it with IP urethane
Dilute the solution with A to 5 to 20 g, and pour this solution into a gap with E.
Apply to the gap 4 between the lower substrates 1 and 2. Mask the lead part to prevent it from being exposed to solution to prevent deterioration of conductivity.
上記のように構成した液晶表示素子について実験したと
ころ、５５℃９５チ湿度でｌθ〜３０ｖのリード間電圧
で３００〜５００時間耐えることができた。When the liquid crystal display device constructed as described above was tested, it was able to withstand 300 to 500 hours at 55° C., 95° C., and humidity with an inter-lead voltage of lθ to 30 V.
本発明によれば、上下基板の周囲の隙間を樹脂でうめて
なるので、ごみ、水分などが入り込むことがなく、信頼
性が向トする。According to the present invention, since the gap around the upper and lower substrates is filled with resin, dust, moisture, etc. do not enter, and reliability is improved.
