<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device for performing stable image display while switching motion image display and still image display. <P>SOLUTION: A liquid crystal display device comprises 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 via a data line. The protection circuit includes a first terminal to which a first power supply potential is supplied and a second terminal to which a second power supply potential higher than the first power supply potential is supplied. In a motion image display mode, an image signal is input to the liquid crystal element from the data line via the transistor, and the first power supply potential is set at a first potential. In a still image display mode, the input of the image signal from the data line to the liquid crystal element is stopped and the first power supply potential is set at a second potential higher than the first potential. The second potential is the same potential as the minimum value of the image signal or is the potential close to the minimum value of the image signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
