ABSTRACT:
A method for driving a twisted nematic type liquid crystal shutter, the liquid crystal shutter having a pair of transparent substrates held opposite to each other; a pair of patterned transparent electrodes each formed on the planes of the transparent substrates and arranged opposite to each other so that the overlapping parts of the patterns form display pixels; a pair of aligning film each formed on the pattern of the transparent electrode and on the plane; a liquid crystal material contained in a space between the transparent substrates; and a pair of transmission type polarizers each arranged on the outside plane of the transparent substrate which is counter to the plane on which the patterned transparent electrode is formed, comprising the steps of: applying an electric voltage to establish static or multiplex driving to the transparent electrodes so as to prevent the transmission of incident light when no image signal is received from an external apparatus; and preventing the application of the electric voltage to transparent electrodes which relate to the pixels selected by the image signal so as to permit the transmission incident light when the image signal is received from the external apparatus.
