A liquid crystal display device used in miniaturized portable equipment includes a distribution circuit corresponding to a circuit scale of a drive circuit to cope with a high-definition multi-grayscale display. A liquid crystal display device which is constituted of a liquid crystal display element and a liquid crystal drive circuit includes a distribution circuit which distributes an output of a drive circuit to a plurality of video signal lines within one scanning period, the distribution circuit is divided into a plurality of distribution circuits, and control signals are supplied to each distribution circuit from both end portions of the each distribution circuit. Further, 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.
