Liquid crystal display device having a gray-scale voltage producing circuit

Abstract

A liquid crystal display device includes a plurality of pixels arranged in a matrix, a plurality of video signal lines for supplying video signal voltages to the pixels, respectively, and a drive circuit for selecting a voltage level of a gray scale voltage varying periodically. As one of the video signal voltages corresponding to display data to be supplied to one of the plurality of pixels. The drive circuit has a plurality of processing circuits connected to each other in series by a processing result transmitting line, and display data lines are formed to intersect with the processing result transmitting line for supplying the display data to the processing circuits. The processing circuits are arranged in correspondence with crossing points of the display data lines and the processing result transmitting line.
