  • Publication number: 20050162362
    Abstract: An image display apparatus and method that provides a flicker-proof thin-film-transistor liquid-crystal-display (TFT-LCD) is provided. The TFT-LCD has a first pixel circuit group having a plurality of first pixel circuits each having a first capacitance; a second pixel circuit group having a plurality of second pixel circuits each having a second capacitance; and a third pixel circuit group having a plurality of the first pixel circuits and the second pixel circuits arranged in accordance with a weighted average of m number of first pixel circuits and n number of second pixel circuits. The m and n first and second pixel circuits form an average third capacitance greater than the first capacitance of the plurality of first pixel circuits but less than the second capacitance of the plurality of second pixel circuits, wherein m and n are positive integers. The pixel circuit groups are formed on a matrix substrate.

  • Patent number: 5680187
    Abstract: To obtain a liquid crystal display device which has no leakage of light and has excellent contrast in the minimum number of manufacturing processes. To obtain cell gap Ga on the array panel 12, first projecting sections 38A are formed in a black matrix 38, and, on the color filter panel 13, second projecting sections 50 are formed in which a red color filter 46R, a green color filter 46G, and a blue color filter 46B are placed one upon another. Since the heights of the first projecting sections 38A and the second projecting sections 50 can be made, for instance, half of cell gap Ga, the rubbing process of orientation films 40 and 54 can be performed reliably. In this way, liquid crystal elements can be fully aligned, preventing the leakage of light. Further, since no transparent spacer is required, there is no leakage of light due to this. In addition, the projecting sections can be formed simply by the processes for forming the color filter 46 and the black matrix 38.
