ABSTRACT:
Each pixel consists of an image electrode formed on a first insulating substrate, a ferroelectrlc material portion formed on the image electrode, a pixel electrode formed on the ferroelectric material layer, a scanning electrode formed on a second insulating substrate, and a liquid crystal portion disposed between the pixel electrode and the scanning electrode. When an input signal is written to the respective pixels, a liquid crystal portion of each of pixels selected for display is supplied with an effective voltage that makes a transmittance of the liquid crystal portion smaller than 50%.
