ABSTRACT:
An image display device includes an operational amplifier, a signal amplifier provided with a condenser for setting a gain of the operational amplifier, a signal amplifier circuit having such signal amplifier or a buffer amplifier, the signal amplifier circuit being provided with an offset adjusting function, and a data signal line drive circuit having a signal amplifier or a signal line drive circuit. The described arrangement enables the gain of the signal amplifier to be set by a capacitance of the condenser, thereby providing a signal amplifier circuit which permits the gain to be set much more precisely as compared to the conventional signal amplifier circuits even when adopting a signal amplifier formed on a semiconductor thin film such as a polycrystalline silicone thin film. The arrangement also provides a signal amplifier circuit which permits a voltage in the same level as a voltage of the input signal to be outputted. Furthermore, the arrangement provides high quality data signal line drive circuit and the image display device.
