Abstract
An insulated-gate transistor signal input device includes an insulating substrate, a first clock line formed on the insulating substrate to receive a clock signal externally supplied, a clock buffer formed on the insulating substrate to process the clock signal supplied from the first clock line, a second clock line formed on the insulating substrate to input a signal obtained from the clock buffer to a shift register serving as a load circuit formed on the insulating substrate. The insulated-gate transistor signal input device further includes a first protection diode circuit connected to the first clock line to remove electrostatic charge from the first clock line, and a second protection diode circuit connected to the second clock line to remove electrostatic charge from the second clock line.
