摘要： In order to achieve lower power consumption, a technique of performing display (partial display) by utilizing only a part of a display area is used. For example, a display area is divided, a plurality of driver circuits for driving the divided display areas independently are provided, and only a region where a fixed pattern is displayed is driven in a power saving mode, thereby partial display is performed; however, display cannot be performed at an arbitrary position. Alternatively, partial display can be performed by inputting a video signal to a pixel in an arbitrary display area; however, a structure of a driver circuit is complicated. The object of the invention is to provide a display device which can perform partial display at an arbitrary position and reduce power consumption. In partial display, operation of a signal line driver circuit is set so as to be stopped and a non-display signal is set so as to be outputted from the signal line driver circuit when a pixel in a non-display area is selected.

摘要： An object is to provide a driving method of a liquid crystal display device with a low power consumption and a high image quality. A pixel includes a liquid crystal element and a transistor which controls supply of an image signal to the liquid crystal element. The transistor includes, in a channel formation region, a semiconductor which has a wider band gap than a silicon semiconductor and has a lower intrinsic carrier density than silicon, and has an extremely low off-state current. In inversion driving of pixels, image signals having opposite polarities are input to a pair of signal lines between which a pixel electrode is disposed. By employing such a structure, the quality of the displayed image can be increased even in the absence of a capacitor in the pixel.
