Abstract:
1. A display provided with a shift register circuit including a first circuit part comprising: a first conductive type of first transistor connected to a first potential side and turned on in response to a clock signal; a first conductive type of second transistor connected to a second potential side; a first conductive type of third transistor connected between a gate of said first transistor and said second potential; and a first conductive type of fourth transistor connected between a clock signal line and the gate of said first transistor and turned on in response to a first signal to supply said clock signal to said first transistor, and a second circuit part comprising: a first conductive type of fifth transistor connected to said first potential side and turned on in response to said clock signal; a first conductive type of sixth transistor connected to said second potential side; a first conductive type of seventh transistor connected between a gate of said fifth transistor and said second potential; and a first conductive type of eighth transistor connected between said clock signal line and the gate of said fifth transistor and turned on in response to a second signal by which a period of on state which does not overlap with a period of on state of said fourth transistor to which said first signal is input is obtained, to supply said clock signal to said fifth transistor.
