Patent ID: 8369478

Claim:
A pulse signal output circuit comprising: a first transistor; a second transistor; a third transistor; a fourth transistor; a first input signal generation circuit; and a second input signal generation circuit, wherein a first terminal of the first transistor and a first terminal of the second transistor are electrically connected to each other to function as a first output terminal, wherein a first terminal of the third transistor and a first terminal of the fourth transistor are electrically connected to each other to function as a second output terminal, wherein a gate terminal of the first transistor, a gate terminal of the third transistor, and an output terminal of the first input signal generation circuit are electrically connected to each other, wherein a gate terminal of the second transistor, a gate terminal of the fourth transistor, and an output terminal of the second input signal generation circuit are electrically connected to each other, wherein a first clock signal is input to a second terminal of the first transistor, wherein a first potential is applied to a second terminal of the second transistor, wherein a second potential which is higher than the first potential is applied to a second terminal of the third transistor, wherein the first potential is applied to a second terminal of the fourth transistor, wherein at least a first pulse signal is input to the first input signal generation circuit, wherein at least a second clock signal is input to the second input signal generation circuit, and wherein a second pulse signal is output from one of the first output terminal and the second output terminal.
