用いているために帯電し易く、この結果、液晶表示素子
たとえばアクティブ型における薄膜トランジスタ（ＴＦ
Ｔ）等の静電破壊を招くという課題がある。However, in the above-mentioned conventional type, since the organic insulating sheet is used as the polarizing plate material, it is easy to be charged. As a result, a liquid crystal display element such as an active type thin film transistor (TF) is used.
There is a problem of causing electrostatic breakdown such as T).

下することになる。従って、本発明の目的は、偏光板を
導電性することなく、液晶表示素子の静電破壊を防止す
ることにある。Incidentally, in order to prevent the above-mentioned electrostatic breakdown,
It has been proposed to make a polarizing plate conductive (see: JP-A-61-138901, JP-A-62-6751).
No. 5). However, the sheet resistance of the polarizing plate is still as high as 10 4 Ω / □, and as a result, the discharge time constant is as long as several minutes, the processing speed is reduced, and the manufacturing cost of the polarizing plate is increased. In order to reduce the sheet resistance of the polarizing plate to 10 2 Ω / □, it is conceivable to form an ITO film by sputtering. However, in this case, the underlayer is limited and the manufacturing cost of the polarizing plate is increased. Moreover, the transparency of the polarizing plate is also reduced. Accordingly, it is an object of the present invention to prevent electrostatic breakdown of a liquid crystal display element without making a polarizing plate conductive.
