Abstract
An improved method of manufacturing liquid crystal devices is described. The liquid crystal device consists of a pair of substrates, a liquid crystal layer disposed between the substrates, an electrode arrangement including driving devices for applying an electric field to the liquid crystal layer. The driving device is formed of a semiconductor film having a pin junction. The method includes the step of repairing short current paths present in the semiconductor film by applying a reverse voltage to the driving device.
