液晶表示素子には種々の表示方式があるが、最も一般的
な方式はツィステッド・ネマチック（Ｉ゛Ｎ）方式であ
る。There are various display methods for liquid crystal display elements, but the most common method is the twisted nematic (IN) method.
この方式は第１図、第２図番こ示すように、配向処理を
行なった２枚の電極基板１．２の周囲をシール材３でシ
ールし、内部に液晶４を封入して液晶セルを構成する。As shown in Figures 1 and 2, this method seals the periphery of two electrode substrates 1 and 2 that have been subjected to alignment treatment with a sealing material 3, and seals the liquid crystal 4 inside to form a liquid crystal cell. Configure.

光板６を電極基板１に貼付けた後に剥離される。A polarizing plate 6 with a protective film 5 is pasted on the outside of the upper electrode substrate 1 of the liquid crystal cell configured in this way, and the lower electrode substrate 2 is attached.
A reflective liquid crystal display element is constructed by attaching a polarizing plate 7 and a reflecting plate 8 to the outside of the display panel. The protective film 5 is peeled off after the polarizing plate 6 is attached to the electrode substrate 1.

め靜゛鑞気により配向膜及び液晶４の劣化を起すと共に
、周辺のＬＳＩの破壊を起すこともある。On the other hand, the polarizing plates 6'' and 7 are made by adding a substance such as iodine to plastic and stretching it.As the polarizing plates 6 and 7 are made of plastic material, they are electrically insulating. For this reason, static electricity is generated and accumulated when the protective film 5 is separated or when the imprint 2 is removed after pasting on the liquid crystal cell.For this reason, the alignment film and the liquid crystal 4 are damaged by the cold air. In addition to causing deterioration of the LSI, it may also cause destruction of the surrounding LSI.
本発明の目的は、偏光板に発生する静電気を防止するこ
とができる液晶表示素子を提供することにある。An object of the present invention is to provide a liquid crystal display element that can prevent static electricity generated in polarizing plates.
