  • Publication number: 20100007811
    Abstract: A liquid crystal display according to an exemplary embodiment of the present invention includes a colored subsidiary light blocking member covering a space between first and second pixel electrodes. First and third shield electrodes are placed under a data line. The first and third shield electrodes are disposed parallel to the data line and across the data line from each other. A second shield electrode connects the bottom end of the first shield electrode with the top end of the third shield electrode at an angle of about 30 degrees to about 150 degrees. With this structure, light leakage at a gap between the pixel electrode and a possible short between the shield electrodes are prevented.

  • 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.

  • Publication number: 20070200984
    Abstract: Disclosed are a reflection type LCD and method of manufacturing the same. A wiring layer having a first and second metal layer (102, 104) is formed on a substrate (100) including a display region (D) and a pad region (P). Upon the substrate (100) and the wiring layer is formed a first passivation layer (155), and contacts with a wiring terminal (115) and the first metal layer (102). A second passivation layer (180) is formed on the substrate except the pad region (P). The pad contact hole (160) extends to a position under the second passivation layer (180). The second passivation layer (180) covers a region in the pad contact hold (160) where the step coverage of the pad electrode (170) is poor, thereby preventing a battery effect.
