Liquid crystal display devices and their method of manufacture.

摘要

A method of manufacturing an active matrix addressed liquid crystal display device consisting of an array of individual picture elements (10) comprising picture element electrodes (20) on a transparent substrate (25) controlled by switching elements (16) connected to at least one set of parallel address conductors (12, 14) of opaque material formed on the substrate involves forming the electrodes (20) after the address conductors by an autoregistration process using the address conductors to define edges of the electrodes. Opposite edges of the electrodes are thus aligned with respective facing edges of adjacent address conductors of the one set or, in the case of crossing row and column conductor sets being provided on the substrate, both sets. The device's active area is thereby maximised and uncontrolled areas minimised.
