  • Patent number: 9158147
    Abstract: A liquid crystal display device includes first and second substrates and a liquid crystal layer interposed therebetween; a gate line, a data line and a common line over the first substrate in the display area; a thin film transistor connected to the gate line and the data line; a color filter layer over the thin film transistor; a first passivation layer over the color filter layer; an auxiliary common line, inner common electrodes and pixel electrodes over the first passivation layer, wherein the auxiliary common line includes a vertical portion and a horizontal portion, the inner common electrodes extend from the horizontal portion, and the pixel electrodes alternate the inner common electrodes; a light blocking pattern in the non-display area, wherein the light blocking pattern includes the same materials as the color filter layer.

  • Patent number: 7961287
    Abstract: An LCD device is disclosed in which column spacers for a cell gap are arranged between gate and common lines to reduce a contact area between the column spacers and an opposing substrate, and a stable cell gap is maintained over the whole panel by reducing variation of a thickness per area of a thin film transistor (TFT) substrate corresponding to the column spacers. The LCD device includes first and second substrates facing each other, gate and data lines formed on the first substrate to cross each other, and pixel regions, a thin film transistor formed in each portion where the gate and data lines cross, common and pixel electrodes alternately formed in the pixel regions, common lines formed adjacent to the gate lines substantially parallel to the gate lines, a first column spacer formed on the second substrate corresponding to a portion between the gate line and the common line, and a liquid crystal layer filled between the first and second substrates.

  • Patent number: 7656496
    Abstract: A liquid crystal display (LCD) device is divided into an active region and a liquid crystal margin region. The LCD includes a thin film transistor substrate that includes gate and data lines crossing each other to define pixel regions, and thin film transistors in the active region. A color filter substrate has column spacers in the active region that contact a portion corresponding to a region of the thin film transistor and the gate or data lines. The column spacers contacting the thin film transistor region provide an elastic gap between the substrates. The column spacers in the gate/data line region are separated from the color filter substrate. Other column spacers are formed in the liquid crystal margin region in a honeycomb arrangement. A liquid crystal layer is disposed between the thin film transistor and color filter substrates.
