Abstract: Provided is a liquid crystal display device having a pixel including a transistor and a liquid crystal element and a protection circuit electrically connected to one of a source and a drain of the transistor through a data line. The protection circuit includes a first terminal supplied with a first power supply potential and a second terminal supplied with a second power supply potential higher than the first power supply potential. In a moving image display mode, an image signal is input from the data line to the liquid crystal element through the transistor, and the first power supply potential is set at the first potential. In a still image display mode, supply of the image signal is stopped, and the first power supply potential is set at the second potential.

Abstract: Provided is a highly reliable semiconductor device. The present invention relates to a shift register circuit including a plurality of stages of sequential circuits. An output signal of a sequential circuit is input to a sequential circuit in the subsequent stage. Before a sequential circuit outputs a signal and after the sequential circuit outputs the signal, the potential of a gate of a transistor included in the sequential circuit is changed in accordance with a clock signal so as to avoid voltage stress application between the gate and a source of the transistor for a long time. The shift register circuit can be applied to a scan line driver circuit of a display apparatus, for example.
