Abstract:
1. A display device comprising: a plurality of gate signal lines disposed in a predetermined direction on a substrate; a plurality of drain signal lines disposed on the substrate in a direction different from the predetermined direction; a plurality of pixel elements which are disposed on the substrate as a matrix, each of the pixel elements being activated by a scanning signal fed through a corresponding gate signal line and provided with an image signal fed through a corresponding drain signal line; a retaining circuit provided in at least one of the pixel elements in which a digital image signal fed from the corresponding drain signal line is written in response to the scanning signal fed from the corresponding gate signal line; and a voltage booster which raises a power voltage supplied to the retaining circuit after a completion of writing of the digital image signal; wherein an output of the retaining circuit determines a representation of an image displayed in the display device.
