  • Patent number: 8035104
    Abstract: The present invention relates to a thin film transistor array panel that includes an organic layer formed on a data line and a drain electrode disposed on a color filter. A thickness of a portion of the organic layer around a contact hole exposing a portion of the drain electrode is similar to a thickness of a portion of the organic layer around a contact hole exposing a portion of the data line. Having approximately the same thickness can prevent non-uniform etching of the organic layer around contact holes and deterioration of the thin film transistor array panel.

  • Publication number: 20080042956
    Abstract: In a display panel, gate lines, data lines, pixel electrodes and a trap electrode are formed on a second display substrate. The gate lines are extended in a first direction, and the data lines are extended in a second direction while insulating from and intersecting with the gate lines. The pixel electrodes may have a W shape rotated in a counter-clockwise direction. The trap electrode is formed in a black matrix area among the pixel electrodes and a different voltage (e.g. a gate-off voltage) from the pixel voltage applied to the pixel electrodes is applied to the trap electrode. Thus, ion impurities in the display panel are trapped into the black matrix area, thereby removing an image sticking caused by the ion impurities.
