  • Publication number: 20100079690
    Abstract: A liquid crystal display includes a substrate, a plurality of a gate line and a plurality of a data line disposed on the substrate, a plurality of a thin film transistor each connected to a gate line and a data line, a plurality of a pixel electrode each connected to a thin film transistor, a common electrode facing the pixel electrodes, and a liquid crystal layer between the pixel electrodes and the common electrode. Each of the pixel electrodes includes a first longitudinal edge adjacent to a first data line and a second longitudinal edge adjacent to a second data line adjacent to the first data line. A first distance between an edge of the first longitudinal edge and the first data line is larger than a second distance between the second longitudinal edge and an edge of the second data line.

  • Publication number: 20100013743
    Abstract: A display device according to an exemplary embodiment of the present invention includes: a substrate, a plurality of gate lines formed on the substrate, a plurality of data lines formed on the substrate, a plurality of switching elements connected to the gate lines and the data lines, a plurality of clock signal transmitting lines formed on the substrate, and a gate driver connected to the gate lines and the clock signal transmitting lines. A direction of each of the clock signal transmitting lines is changed approximately ninety degrees in a first region and a second region. The regions are disposed between an edge of the substrate and the gate driver. A symmetry is present between portions of the clock signal transmitting lines arranged in the first region and the second region.

  • Publication number: 20100007839
    Abstract: In a display substrate and a vertical alignment display panel having the same, the display panel includes an array substrate and an opposite substrate. A plurality of first slit portions are arranged through a pixel area of a common electrode on the array substrate, and the first slit portions extend in a slanted direction. A plurality of grooves and a plurality of protruding portions are alternately arranged at edges facing each other on the first slit portion, so that the first slit portions are patterned. A positive singular point is generated on a side surface of a protruding portion, and a negative singular point is generated between the positive singular points.
