  • Publication number: 20070128401
    Abstract: The present invention discloses an electrode separator, which is formed on a substrate that has strip-like first electrodes and is perpendicular to the first electrodes, wherein a common positive type photoresist material is firstly obliquely exposed and then vertically exposed and then developed to form the electrode separator by the two exposure steps. The electrode separator has a first lateral vertical to the bottom side of the electrode separator and a second lateral cooperating with the surface of the substrate to create an acute angle with one end of the top side having an overhanging portion. When the second electrodes are deposited, the overhanging portions can separate the metallic film of the second electrodes, and the metallic film of each second electrode is confined to between two electrode separators. Thus, the objective of separating the second electrode is achieved.

  • Publication number: 20070058096
    Abstract: The present invention is a storage capacitor structure for liquid crystal display panels, by using a portion of the pixel electrode formed by the transparent metal layer that is overlapped and corresponding to the common electrode of the second metal layer, which is used as the storage capacitor for the pixel. The common electrode is also used as the second metal layer of the pixel, which shields unnecessary light of the backlight module to raise the contrast ratio of the whole display panel.
