Abstract
In each of unit circuits that constitute a shift register, a first conduction terminal of a second thin-film transistor that controls the output of an output signal serving as a scanning signal is given a second input clock signal having a amplitude larger than the amplitude of a first input clock signal that is given to a first conduction terminal of a first thin-film transistor that controls the output of an output signal serving as a control signal for controlling another unit circuit. The channel length of the second thin-film transistor is set to be greater than the channel length of the first thin-film transistor, so that the breakdown voltage of the second thin-film transistor is higher than the breakdown voltage of the first thin-film transistor.
