  • Patent number: 8013964
    Abstract: A liquid crystal display device uses a first quarter-wave retardation film and a hybrid aligned nematic film to reduce light leakage in dark state for reaching high contrast ratio, and uses multiple-gamma IC to provide different gamma-curve signals for pixels of different colors to solve color shift problem. In addition, the liquid crystal display device may use a second quarter-wave retardation film to reduce light leakage when viewed in a wide angle so as to further provide higher contrast ratio.

    Abstract: A pixel structure of a liquid crystal display panel includes a first transparent substrate, a first data line, a second data line, a transparent electrode, and a compensating conducting pattern layer. In a display region, the first side of the transparent electrode and the first data line partially overlap, forming a first parasitic capacitor, the second side of the transparent electrode and the second data line partially overlap, forming a second parasitic capacitor smaller than the first parasitic capacitor. In a non-display region, the first side of the transparent electrode and the first data line partially overlap, forming a third parasitic capacitor, and the second side of the transparent electrode and the compensating conducing pattern layer partially overlap, forming a fourth parasitic capacitor.

  • Patent number: 7894025
    Abstract: An LCD including a color filter substrate, an array substrate, and a liquid crystal layer therebetween is provided. This color filter substrate has a plurality of color filters with overlap regions acting as a black matrix. Subsequently, patterned regions are defined in part of the overlap regions. After formation of a planarization layer and a conductive layer, spacers are formed in the patterned regions. The spacers may not shield the transparent region of the color filters, thereby enhancing the aperture ratio of the color filter substrate. Additionally, the thickness of the planarization layer in the patterned regions is not influenced by the overlap of the color filters, such that the spacers thereon have a uniform height. Furthermore, the at least one spacer of the color filter substrate and at least one data line of the array substrate are overlapped.
