ABSTRACT:
The display device of this invention, in which the retaining circuit for retaining the image signal is provided for each of the pixel elements, is capable of operating under two operation modes, a normal operation mode and a memory mode. Since the placement of the retaining circuit110,which requires relatively large area, is confined to the area for the pixel element electrode17not in between the neighboring pixel element electrodes17,the required area for one pixel element is minimized, resulting in the size reduction of the liquid crystal display device. By placing at least a portion of the retaining circuit in the area of the pixel element electrode17of the neighboring pixel element, the detour of the wiring can be omitted, resulting in the efficient use of the space. By this, the area required for the retaining circuit is minimized, directly resulting in the reduction of the size of the liquid crystal display device.
