Abstract

PURPOSE:To obtain a liq. crystal display element enabling high-speed response and action in a wide temp. range by sticking a polarizing plate provided with an adhesive and an electrically conductive transparent film to a liq. crystal display element and by using the polarizing plate as a heater. CONSTITUTION:A plastic film 2 provided with an electrically conductive transparent film is stuck to the underside of an under polarizing plate 1 for a TN type liq. crystal display element with an adhesive. The under glass substrate 3 of the element, the upper glass substrate 4 and an upper polarizing plate 5 are arranged under the plate 1 in order. The film 2 is stuck to the plate 1 in a stage for sticking the plate 1 to the element. The positional relation of the film 2 to the plate 1 may be inverted, and the film 2 may be placed at the side of the plate 5.

Description

【発明の詳細な説明】 本発明は液晶表示素子（以下、ＬＣＤという）の改良に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in liquid crystal display elements (hereinafter referred to as LCDs).

ＬｃＤｌこ高速応答性、広動作温度範囲が要求される場

の方法はコストが高く、また実装上大きな容積が必要等
の問題がある。ｆａ２の方法はプロセス的ｌこ製作が困
難で、またそのためコストが高くなる等の問題がある。It is known that when a high-speed response and a wide operating temperature range are required, the LCD can be heated by some method. The first method is to provide a heater outside the LCD. A second method is to form a transparent conductive film other than that for display on a glass substrate constituting an LCD, and use it as a heater by passing an electric current through the film. However, the first
This method is expensive and requires a large volume for mounting. The fa2 method has problems such as difficulty in process-wise manufacturing and high cost.

本発明の目的は、ヒータをプロセス的に容易にしかも低
コストで実現できるヒータ付きＬＣＤを提供することに
ある。SUMMARY OF THE INVENTION An object of the present invention is to provide an LCD with a heater that can be realized easily in terms of process and at low cost.

以下、本発明の一実施例を図により説明する。Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

図は通常のＴＮ形ＬＣＤの下偏光板１の下に透明導電膜
付プラスチックフィルム２を粘着剤により貼り付けたも
のである。なお、３は下板ガラス基板、４は上板ガラス
基板、５は上偏光板を示す。The figure shows an ordinary TN type LCD in which a transparent conductive film-coated plastic film 2 is pasted under a lower polarizing plate 1 with an adhesive. Note that 3 indicates a lower glass substrate, 4 indicates an upper glass substrate, and 5 indicates an upper polarizing plate.

前記プラスチックフィルム２の貼り付けは偏光板をＬＣ
Ｄに貼り付けるプロセスとまったく同じプロセスででき

Ｄと同様にゼブラ形インターコネクターあるいはリード
ピン方式等が可能である。When pasting the plastic film 2, the polarizing plate is attached to the LC.
You can do it using the exact same process as pasting it to D. Also, the input to this plastic film 2 is LC
Similar to D, a zebra-shaped interconnector or lead pin method is possible.

このプラスチックフィルム２の貼り付けは、図において
下偏光板１との位置関係を逆転することは可能である。When attaching this plastic film 2, it is possible to reverse the positional relationship with the lower polarizing plate 1 in the figure.

さらに上偏光板５儒へ配置することも可能である。また
透明導電膜付偏光板を上記プラスチックフィルムの代り
に使用すれば、さらにプロセス的、コスト的に有利にな
る。Furthermore, it is also possible to arrange the upper polarizing plate 5. Moreover, if a polarizing plate with a transparent conductive film is used instead of the above-mentioned plastic film, it will be more advantageous in terms of process and cost.

以上の説明から明らかな如く、本発明によれば、高速応
答、広温度範囲動作可能なヒータ付ＬＣＤをプロセス的
番こ容易に、低コストで実現できる。As is clear from the above description, according to the present invention, a heater-equipped LCD capable of high-speed response and operation over a wide temperature range can be realized with ease in process control and at low cost.
