ABSTRACT:
A liquid crystal display device having analog buffer circuits is provided which is reduced in luminance fluctuation. A source signal line driving circuit has a plurality of analog buffer circuits. 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. Output fluctuation among the analog buffer circuits is thus averaged and a uniform image can be displayed on the screen.
