An object of the present invention is to suppress malfunctions in a shift register circuit. A shift register having a plurality of flip-flop circuits is provided. The flip-flop circuit includes a transistor (11), a transistor (12), a transistor (13), a transistor (14), and a transistor (15). When the transistor (13) or the transistor (14) is turned on in a non-selection period, the potential of a node (A) is set, so that the node (A) is prevented from entering into a floating state. |
