Abstract

The shift register includes first to fourth flip-flops. A first clock signal which is in a first voltage state in a first period and in a second voltage state in second to fourth periods is input to the first flip-flop. A second clock signal which is in the first voltage state in the second period and in the second voltage state in the third period and the fourth period is input to the second flip-flop. A third clock signal which is in the second voltage state in the first, second, and fourth periods and in the first voltage state in the third period is input to the third flip-flop. A fourth clock signal which is in the second voltage state in the first and second periods and in the first voltage state in the fourth period is input to the fourth flip-flop.
