摘要： A liquid crystal display device has a liquid crystal composition sandwiched between a pair of substrates, and a plurality of pixels disposed on one of the first substrates. Each of the pixels is supplied with a video signal via a switching element connected to a first electrode thereof, and is provided with a capacitance. One of two capacitance-forming electrodes forming the capacitance is connected to the first electrode of a corresponding one of the pixels, and another of the two capacitance-forming electrodes is supplied with a pixel-potential control signal. Polarity of the video signal reverses with respect to a first reference voltage with a repetition period, and the pixel-potential control signal alternates between two voltage levels of same polarity with respect to a second reference voltage such that a voltage swing on the first electrodes of the pixels becomes larger than that of the video signal.

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 liquid crystal light valve for a projection type display such that a pixel circuit area in which a plurality of switching elements are disposed in a matrix state, a drive circuit area in which drive circuit elements are disposed, and the peripheral area are formed on the surface of a semiconductor substrate and further metal layers are provided through insulating layers. The uppermost layer of the metal layers are partitioned by slits to arrange reflectors as output terminals of the switching elements. As middle layers, a shading layer of the pixel circuit area for interrupting an incident light from the slits and a shading layer for interrupting an irradiation to the peripheral area and the drive circuit area are formed. Further, when image data to be displayed in the pixel circuit area has a construction of n.times.m pixels (where, n and m are even numbers), the number of columns and the number of lines are increased by one, respectively, thereby obtaining a construction of (n+1).times.(m+1) pixels.
