た。The conventional liquid crystal display element with touch panel function is
As shown in the figure, it has a structure in which a touch panel 2 is mounted on a liquid crystal display element 1. (For example, 1986-126
(See Publication No. 58) [Problems to be Solved by the Invention] In the above conventional example, it is difficult to align the display pattern of the liquid crystal display element 1 and the display pattern of the touch panel 2;
Workability (poor) Also, since it has a two-layer structure of the liquid crystal layer of the touch panel 2 and the liquid crystal layer of the liquid crystal display element 1, the light transmittance is poor. However, if such a television becomes portable, it is necessary to provide a touch panel on the LCD screen.
If a touch panel is provided on the TV screen, the light transmittance will be poor, which poses a problem as a product. In addition, in the conventional example,
There were also problems in that there were a large number of parts and the cost was high.
本発明の目的は、光の透過率を上げることができ、また
作業性に優れ、かつ部品点数の削減が図れる液晶表示素
子を提供することｌこある。An object of the present invention is to provide a liquid crystal display element that can increase light transmittance, has excellent workability, and can reduce the number of parts.
上記問題点は、２枚の電極基板の対向面１こ、それぞれ
液晶点灯用電極パターンとタッチパネル用電極パターン
とを設けることｌこより解決される。The above problem can be solved by providing a liquid crystal lighting electrode pattern and a touch panel electrode pattern on the opposing surfaces of two electrode substrates, respectively.
液晶層は一層よりなるので、光の透過率が低下すること

ンとタッチパネル用電極パターンとを設けるので、作業
性ｌこ優れている。また通常の液晶表示素子と部品点数
が同じであり、部品点数が増えることもない。Since the liquid crystal layer is made of one layer, the light transmittance does not decrease. Further, since the inner surface of the electrode substrate is provided with an electrode pattern for lighting the liquid crystal and an electrode pattern for the touch panel, the workability is excellent. Furthermore, the number of parts is the same as that of a normal liquid crystal display element, so the number of parts does not increase.
以下、本発明の一実施例を第１図により説明する。２枚

０が設けられている。An embodiment of the present invention will be described below with reference to FIG. Touch panel electrode patterns 5.6 are provided on the opposing surfaces of the two glass substrates 3.4, and a normal liquid crystal lighting electrode pattern 9.1 is provided thereon via a G insulation film 7.8.
0 is set.

ている。Then, sealing material 1 is applied to the periphery of the two glass substrates 3.4.
1, and an internal liquid crystal 12 is sealed. Further, external terminals of the touch panel electrode pattern 5.6 and the liquid crystal lighting electrode pattern 9.10 are respectively connected to a liquid crystal capacitance detector and an external drive circuit (not shown).
従って、タッチパネル用電極パターン５．６の表示は、

灯する。Therefore, the display of the touch panel electrode pattern 5.6 is as follows.
When pressure is applied to the surface of the glass substrate 3, the capacitance of the liquid crystal 12 changes, so a liquid crystal capacitance detector (not shown) detects this change in Wt, and the touch panel electrode pattern 5.6 lights up.

するこ吉もなく、また部品点数が増えることもない。In this way, on the same glass substrate 3.4, the touch panel electrode pattern 5.6 and the liquid crystal lighting electrode pattern 9.
10, it is easy to align the two, and the workability is excellent. Furthermore, since the touch panel electrode patterns 5 and 6 are provided within the liquid crystal display element, there is no risk of a decrease in light transmittance, and there is no increase in the number of parts.
