摘要： A display device which stores display data for every display pixel can reduce the number of transistors which constitute 1 display pixel. In a display device which includes a display panel having a plurality of display pixels, video lines which apply video data to the display pixels and scanning lines which apply a scanning voltage to the display pixels, the display pixel includes: a capacitive element which holds a voltage corresponding to a value of the video data; a pixel electrode; a first transistor of a first conductive type which is connected between a first power source line and the pixel electrode and, at the same time, has a control electrode to which the voltage held in the capacitive element is applied; and a second transistor of a second conductive type different from the first conductive type which is connected between a second power source line and the pixel electrode and, at the same time, has a control electrode to which the voltage held in the capacitive element is applied. Here, a first voltage is supplied to the first power source line, and a second voltage is supplied to the second power source line. The second voltage is a voltage which is obtained by inverting the first voltage.

摘要： The present invention realizes a liquid crystal display device which can be driven with a low voltage while preventing the degradation of liquid crystal by reducing a residual charge of a pixel electrode even when a drive circuit is abnormally stopped. As a field effect transistor which is formed on a pixel, a field effect transistor in a depletion mode which is turned on in a state that an OFF signal is not applied to a gate terminal of the transistor is used. A substrate voltage supply line which supplies a substrate voltage to pixel regions is provided, and the substrate voltage is supplied via a through hole formed in the pixel portion thus controlling an optimum threshold value in response to an input signal. Wiring is made in a peripheral portion of a display region such that video signal lines and the substrate voltage supply line intersect each other.

摘要： A liquid crystal display apparatus has horizontal and vertical scanning circuits for scanning an array of pixels. An image signal applied to an image signal supply circuit in the form of series of pixel signals is transferred to pixels in the array of pixels designated by the horizontal and vertical scanning circuits. Each of the horizontal and vertical scanning circuits have a series connection of bidirectional shift register stages and are capable of bidirectional scanning. Each of the bidirectional shift register stages includes a pair of latches connected in tandem and is capable of providing an intermediate output and a shift register stage output. The pair of latches of each of the bidirectional shift register stages except those located at both ends of the series connection have respective intermediate and bidirectional shift register stage outputs contributing to designation of pixels to which pixel signals are to be supplied, while the pair of latches of the shift register stages located at each end of the series connection have their bidirectional shift register stage outputs contributing to such designation of pixels and their intermediate output terminals not contributing to such designation of pixels.
