Title:
ELECTRO-OPTICAL ELEMENT OF HIGH RELIABILITY AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPS5834433
Kind Code:
A
Abstract:

PURPOSE: To prevent the corrosion of a lead terminal and to enhance the reliability of an electro-optical element, by forming a protecting layer of a conductive material on the lead terminal of the electro-optical element such as a liquid crystal display element, at the outside of the sealed part as partially overlapped therewith.

CONSTITUTION: For instance, a carbon paste or a paste containing a conductive material 10 containing carbon and the metallic powder is screen printed and dried on a lead terminal 4 connected to a display electrode 3 on the inner surface of a display substrate 1 of a liquid crystal display element and at a sealed part 6 caused when the electrode 1 is put on its counter electrode 2 so that the paste enters a ≤50% area of the part 6. The sealing material 6 is printed on the substrate 2, and the substrate 2 is joined to the substrate 1. Then the liquid 7 is enclosed between these two substrates. Thus the terminal 4 can be prevented from the corrosion owing to the water content leaked out of the gap of the part 6 or the interface. As a result, the reliability is enhanced for the electro-optical element.
