ABSTRACT:
Fluctuations in an image quality of an active matrix type display device are reduced. The active matrix type display device is driven by a drive circuit constructed of a shift register, an analog memory constructed of an analog switch and a capacitor, and an analog buffer formed by a thin-film transistor. In this drive circuit, a channel length of the thin-film transistor for constituting said analog buffer is made longer than a channel length of a thin-film transistor for constituting either said analog switch, or said shift register.
