Abstract
A method of manufacturing an active matrix addressed liquid crystal display device consisting of an array of individually controlled picture elements involves forming the electrodes 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 repective facing edges of adjacent address conductors. The device's active area is thereby maximized and uncontrolled areas minimized.
