The peripheral parts of two upper glass substrates 1 and lower glass substrates 2, each having a transparent electrode formed on their opposing surfaces, are sealed with a sealant (not shown), and a liquid crystal material (not shown) is sealed inside, An upper polarizing plate 3 and a lower polarizing plate 4 are attached to the outer sides of an upper glass substrate 1 and a lower glass substrate 2, respectively, via an adhesive. The touch panel has a touch panel function with a transparent electrode 6 formed on a lower touch panel substrate 5 and a transparent electrode 8 formed on an upper touch panel substrate 7.
The periphery of the upper substrate 7 is sealed with a sealing material 9. Then, a sealing material 10 is placed on the upper glass substrate 1 of the liquid crystal display element.
The lower substrate 5 of the touch panel is sealed through the .
この構造は液晶表示素子上に単にタッチパネルをのせた
構造であるので、光透過率が悪く、暗い表示になるとい
う問題点があった。Since this structure simply has a touch panel mounted on a liquid crystal display element, it has a problem of poor light transmittance and a dark display.
そこで、明るいタッチパネルを得るため、タッチパネル

上にシール材９でシールしたものが提供されている。Therefore, in order to obtain a bright touch panel, the lower substrate 5 and upper substrate 7 for the touch panel are wiped off, and as shown in FIG. An electrode 6.8 is formed to provide a touch panel function, and the upper polarizing plate 3 is attached to the upper glass substrate 1.
It is provided that the top is sealed with a sealing material 9.
この構造は上偏光板３表面ｌこ透明電極６を形成するの
で、透明電極６は上偏光板３の偏光子の熱的制限（高温
処理すると偏光機能を失う）により高温処理できなく、
化学的、機械的に強くなく、信頼性上において問題があ
った。In this structure, the transparent electrode 6 is formed on the surface of the upper polarizing plate 3, so the transparent electrode 6 cannot be subjected to high temperature treatment due to thermal limitations of the polarizer of the upper polarizing plate 3 (the polarizing function is lost when treated at high temperature).
It was not chemically or mechanically strong and had reliability problems.
本発明の目的は、化学的、機械的に強く、信頼性の高い
タッチパネル付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 with a touch panel that is chemically and mechanically strong and highly reliable.

構成は第２図と同じである。[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIG. Note that the same or equivalent members as in FIG. 2 will be described with the same reference numerals. A lower polarizing plate 4 is attached to the outside of the lower glass substrate 2 of the liquid crystal display element via an adhesive, and a transparent electrode 6 is formed on the upper glass substrate 1 of the liquid crystal display element. This configuration is the same as in FIG.
