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.

摘要： A photolithography step and an etching step for forming an island-shaped semiconductor layer is omitted, and a liquid crystal display device is manufactured through the following four photolithography steps: a step for forming a gate electrode (including a wiring or the like formed from the same layer), a step for forming a source electrode and a drain electrode (including a wiring or the like formed from the same layer), a step for forming a contact hole (including removal of an insulating layer or the like in a region other than the contact hole), and a step for forming a pixel electrode (including a wiring or the like formed from the same layer). In the step of forming the contact hole, a groove portion in which the semiconductor layer is removed is formed, so that formation of parasitic channels is prevented.

摘要： An object is to provide a display device in which a difference in load capacitance between wirings is reduced in the case where different signals are supplied to plural pixels at the same timing with use of plural wirings; thus, deviation in the grayscale and/or signal delay can be reduced. The display device includes first to N-th (N is a natural number of 3 or larger) data lines for supplying different video signals; and a pixel including a selection transistor connected to one of the first to N-th data lines. The first to N-th data lines intersect with each other so that one of the first to N-th data lines is provided closest to one terminal of the selection transistor and connected to the one terminal of the selection transistor.

摘要： 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. The second potential is substantially the same as the minimum value of the image signal.
