  • Patent number: 6833902
    Abstract: A structure for preventing a liquid from permeating into a cell for facilitating fabrication of a plurality of planels comprising a first substrate having a first exhaust area and a plurality of first portions of the planels, a second substrate having a second exhaust area and a plurality of second portions of the planels, a plurality of orienting films on the plurality of first and second portions of the planels, a plurality of thickening films respectively on the first and the second substrates for narrowing an intermediate distance of the first and second exhaust areas to prevent the liquid from permeating into the cell, a dummy seal around a periphery of the second substrate for preventing the liquid permeating into the cell.

  • Publication number: 20040209389
    Abstract: A protection layer is formed on a transparent substrate having a plurality of thin film transistors, and an exposure step is then carried out by means of a half-tone mask. An outer lead bonding area is located on the periphery of the transparent substrate. After the exposure and development steps, most of the protection layer in the outer lead bonding area is removed. With an etching step, the top of an insulation layer of the outer lead bonding area is exposed and a plurality of via holes are formed in the insulation layer, thus a metal layer is exposed from the via holes as outer lead bonding pads. Finally, a transparent conductive layer with desired patterns is formed on the protection layer, and the transparent conductive layer is extended into the via holes of the protection layer to connect with the thin film transistors.

  • Publication number: 20030049994
    Abstract: A method for polishing a liquid crystal display panel is provided. The liquid crystal display panel is provided with a thin-film transistor substrate that is provided with a pad area thereon. The polishing method comprises the following steps. A protecting member is provided. The protecting member is bonded on the pad area of the thin-film transistor substrate. After the liquid crystal display panel is polished, the protecting member is removed from the thin-film transistor substrate.
