Abstract:
1. A light-reflector for use in a liquid crystal display device which uses externally incident light as a light source by reflecting the externally incident light to a viewer and which includes a plurality of rows of pixels, each row including a plurality of pixels, wherein each of the plurality of pixels comprises a plurality of pixel areas, the light reflector comprising a plurality of light reflector portions, said light reflector portions being formed in one of the plurality of pixel areas of each of said pixels, wherein the light-reflector includes a plurality of thin film transistor switching devices each corresponding to one of the light reflector portions in the plurality of pixels, wherein each light reflector portion is formed with a rugged pattern, including an alternating pattern of N pixel pattern areas, each pixel pattern area of the alternating pattern of N pixel pattern areas positioned to overlie a respective one pixel of said plurality of pixels of said plurality of rows of pixels of the liquid crystal display device, each of the N pixel pattern areas of the alternating pattern being different, wherein each pixel pattern area of the alternating pattern is comprised of recessed and raised portions, wherein said rugged pattern is repeated in every row of pixel areas, and wherein N is an integer greater than one, other than three.
