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.

The circuit includes a plurality of series combinations of processing circuits. Each of the series combinations is associated with one of video signal lines coupled to pixels, and each of the processing circuits of a respective one of the plural series combinations is associated with a respective one of N display data lines for supplying the display data and with a respective one of plural time control signal lines for supplying time control signals varying in synchronism with the gray-scale voltage. Each of the processing circuits is disposed between two adjacent ones of the N display data lines.
