Title:
PRODUCTION OF LIQUID CRYSTAL PANEL SUBSTRATE
Document Type and Number:
Japanese Patent JPS6177032
Kind Code:
A
Abstract:

PURPOSE: To prevent the generation of pinholes in a liquid crystal by patterning a photoresist on a transparent electrode on a transparent substrate and rotating and applying a polyimide solution on this photoresist to form an oriented film and lifting off the photoresist.

CONSTITUTION: A transparent electrode 2 is provided on a transparent substrate 1 consisting of glass or the like, and a positive photoresist 3 is rotated and applied onto the electrode 2. A mask 4 having a prescribed pattern is used to expose it. The photoresist 3 is developed, and exposed parts are eliminated, and a polyimide solution is rotated and applied to these parts and is heated to form an oriented film 5. Unexposed parts 3 of the photoresist are swelled with a developer and are removed together with an oriented film 5' on them by spray water washing. Lead parts 6 and 7 of the transparent electrode are formed. Thus, the thickness of the oriented film 5 is made uniform, and the generation of pinholes is prevented.
