こととなつた。 Conventional liquid crystal display elements as described above have been widely put into practical use as display elements for calculators, wristwatches, etc., but there has been a strong demand for improved reliability. One item of reliability is a moisture resistance operation test, in which a liquid crystal display element is operated by applying a predetermined driving voltage under conditions of a predetermined temperature and a predetermined relative humidity. When a conventional liquid crystal display element is operated under conditions of a temperature of 60°C and a relative humidity of 90%, indium oxide electrolyzes within a relatively short time of several tens of hours if the external terminal 3 is an indium oxide film. As a result, the wire became disconnected and the display function was lost.

However, it is an object of the present invention to provide a display element using a transparent conductive substrate with improved reliability.

A front electrode substrate 1 having a transparent electrode pattern on the back surface and a back electrode substrate 2 having a transparent electrode pattern on the back surface are prepared. After cleaning and drying the front and back electrode substrates 1 and 2, one side having a conductive film is rubbed with a cloth to perform an alignment treatment. Next, a graphite paint containing graphite as a main component is printed by screen printing on the pattern of the external lead-out terminals 3 of the front electrode substrate 1, and dried by heating at a temperature of 150° C. for 30 minutes to form a graphite conductive film 6. Then, an organic adhesive is formed on the periphery of the back surface of the back electrode substrate 2,
The front and back electrode substrates 1 and 2 are adhered with a predetermined gap maintained to produce a liquid crystal display element envelope. Finally, liquid crystal is injected into this liquid crystal display element envelope,
