ABSTRACT:
To provide thin-film transistor circuits used for a driving circuit that realizes a semiconductor display capable of producing an image with high resolution and high precision without image unevenness.TFTs with small channel widths are used to form an analog buffer which comprises a differential amplifier circuit and a current mirror circuit and which is used in a driving circuit of an active matrix semiconductor display. A plurality of such analog buffer circuits are connected in parallel to secure an analog buffer that has a sufficient current capacity.
