ABSTRACT:
A liquid crystal display device which performs a gradation display for each frame, by eliminating fluctuations in pixel voltage. The device includes a pixel electrode and a MOS transistor circuit driving the pixel electrode. The MOS transistor circuit is disposed near a cross-over point of a scanning line and a signal line, and includes a first MOS transistor having a gate electrode connected to the scanning line, and one of a source electrode and a drain electrode connected to the signal line. The MOS transistor circuit also includes a source follower type analog amplifier having an input electrode connected to the other one of the source and drain electrodes of the MOS transistor, one of plural power supply electrodes connected to the scanning line, and an output electrode connected to the pixel electrode.
