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 display device which is used in a miniaturized portable information device can exhibit the low power consumption even when a display is not changed over for a long period in a state that a battery or the like is used as a power source. The display device can maintain a high numerical aperture by suppressing the number of parts even when a memory element is provided to a pixel. In a liquid crystal display device, a pixel exhibits the low power consumption by including a memory element and thus preventing the transmission of a video signal. By making use of a charge held in a pixel electrode of a liquid crystal display panel, a signal for AC driving is formed in the inside of a pixel thus performing AC driving to perform a display without deteriorating liquid crystal even when the video signal is not rewritten. The liquid crystal display device can realize the memory element with the simple constitution without sacrificing a numeral aperture.

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.

摘要： A method for forming a liquid crystal display device includes forming a metal film over a drive substrate, and patterning the metal film to form at least one pixel electrode and an optical shield film. The optical shield film is provided outside of a pixel electrode area and has a width greater than a width of each of the pixel electrode. A resin is deposited over the patterned metal film, and the resin is patterned to form at least one pole spacer and strip spacer. The strip spacer surrounds the pixel electrode area and has a width greater than a diameter of each of pole spacer. Liquid crystal material is supplied into an inside space which is surrounded by the strip spacer, and a sealing material is filled at outer edges of the strip spacer for fixing the drive substrate and a common substrate.
