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： It is an object to provide a display device in which a problem of light leakage from a liquid crystal element in black display is reduced or overcome and the contrast is improved. It is another object to provide a pixel circuit having a function to control a lighting state of a backlight based on each pixel. These objects are achieved by turning off a light-emitting element in display of a black gray scale, and by providing a light-emitting element in each pixel and providing, in a pixel circuit, a function to individually control lighting and non-lighting of the light-emitting element depending on a gray scale to perform display. When a backlight is provided in each pixel, a light-emitting element that is a backlight is turned off when a black gray scale is displayed, whereby reduction in contrast due to light leakage from a liquid crystal element can be prevented.

摘要： To suppress variation of a signal in a semiconductor device. By suppressing the variation, formation of a stripe pattern in displaying an image on a semiconductor device can be suppressed, for example. A distance between two adjacent signal lines which go into a floating state in different periods (G1) is longer than a distance between two adjacent signal lines which go into a floating state in the same period (G0, G2). Consequently, variation in potential of a signal line due to capacitive coupling can be suppressed. For example, in the case where the signal line is a source signal line in an active matrix display device, formation of a stripe pattern in a displayed image can be suppressed.

摘要： An object is to reduce a pseudo contour occurring in time gray scale method display. One pixel is divided into m subpixels (m is an integer of m≧2), and the area of the (s+1)th subpixel (1≦s≦m−1) is twice the area of the s-th subpixel. Further, one frame is divided into n subframes (n is an integer of n≧2), and a lighting period of the (p+1)th subframe (1≦p≦n−1) is 2m times longer than a lighting period of a p-th subframe. Then, at least one subframe of the n subframes is divided into a plurality of subpixels each having a lighting period shorter than that of the subframe so that the n subframes are increased to t subframes (t>n). In at least one subframe of the t subframes, lighting periods of the subframes in a lighting state are sequentially added by the m subpixels, so that a gray scale of the pixel is expressed.
