  • Publication number: 20040189894
    Abstract: An LCD comprises: an upper array substrate and a lower color filter substrate, which are opposed and spaced a predetermined distance to each other; a reflective film formed in a matrix on a non-pixel section on the color filter substrate; a black-matrix formed on the reflective film; red, green, and blue color filters, formed on pixel sections of the color filter substrate defined by the black-matrix; a lower orientation film formed on the whole area of substrates including the color filters and black-matrix; a pixel electrode formed on the pixel section on the array substrate; an upper orientation film formed on the whole area of substrates including the pixel electrode; a liquid crystal layer interposed between the color filter substrate and the array substrate; a partially masked lower polarizer mounted outside the color filter substrate, in which a portion under the non-pixel section does not have polarization function; and an upper polarizer mounted outside the array substrate.

  • Patent number: 6707524
    Abstract: The present invention relates to a fringe field switching mode liquid crystal display, comprising: gate lines and data lines aligned on a transparent insulating substrate to vertically cross each other; common electrode lines aligned horizontally to the gate lines; a pixel region defined in a space formed by the gate lines and data lines; a first transparent electrode formed in the pixel region, and divided into at least two regions; and a second transparent electrode insulated from the first transparent electrode, and divided on the first transparent electrode as many as the first transparent electrode, a data voltage being applied to the second transparent electrode in a first region and to the first transparent electrode in a second region, a sum of the voltages applied to the pixel region having a zero voltage.
