Abstract:
A liquid crystal display device used in miniaturized portable equipment includes a distribution circuit to cope with a high-definition multi-grayscale display. A distribution circuit distributes an output of a drive circuit to a plurality of video signal lines within one scanning period, the distribution circuit being divided into a plurality of distribution circuits, and control signals being supplied to each distribution circuit from both end portions of each distribution circuit. When an output part of the drive circuit is configured such that a high withstand-voltage output amplifier and a low withstand-voltage output amplifier are alternately connected with the distribution circuit, a master function and a slave function are imparted to the drive circuit so as to allow the drive circuit to cope with odd-numbered outputs.
