ABSTRACT:
A method for driving a multi-layered-type liquid crystal display device is disclosed. The liquid crystal display device includes a plurality of cell layers, and each cell layer contains liquid crystal molecules twisted between two transparent substrates so as to have a relatively large birefringence and having a light transmittance changing responsive to a voltage applied thereto. Voltages to be applied to respective cell layers are determined so as to pass a predetermined color light in combination of the light transmittances of individual cell layers. Further, these cell layers are driven by those voltages determined to display an image having the predetermined color light on the liquid crystal display device.
