ABSTRACT:
A liquid crystal display device having analog buffer circuits, which is reduced in luminance fluctuation is provided. A source signal line driver circuit has a plurality of analog buffer circuits, the plurality of source signal lines and the plurality of analog buffer circuits constitute a circuit group, and source signal lines connected to the analog buffer circuits are switched their connections to different analog buffer circuits each time a new period is started. Therefore, output fluctuation among the analog buffer circuits is averaged and a uniform image can be displayed on the screen.
