  • Publication number: 20060060849
    Abstract: An array substrate includes a gate line, a data line, a switching device, a transmissive electrode, a reflective electrode and a compensating wiring. A pixel region includes first and second regions. The switching device is connected to the gate line and the data line. The transmissive electrode is connected to the switching device. The transmissive electrode is formed in the first region. The reflective electrode is insulated from the transmissive electrode. The reflective electrode is formed in the second region that is adjacent to the first region. The compensating wiring is connected to the switching device. The compensating wiring faces the reflective electrode in the second region with an insulation layer interposed therebetween. Thus, both of a reflectivity of the reflective electrode and a transmissivity of the transmissive electrode are enhanced simultaneously, while the liquid crystal display apparatus maintains a uniform cell gap.

  • Publication number: 20050151893
    Abstract: Gate lines are formed on an insulating substrate, and data lines crossing the gate lines are formed. The gate lines and the data lines are insulated from each other and intersect each other to define pixel areas. A thin film transistor including three terminals of a gate electrode, a source electrode and a drain electrode is formed in each pixel area. A direction control electrode and a pixel electrode are also formed in each pixel area. The thin film transistor switches the direction control electrode. The pixel electrode is electronically floating and capacitively coupled with the direction control electrode.

  • Patent number: 4974967
    Abstract: A laundry net is diclosed which includes a net body formed into an octahedron, which is made by stitching four net members of a rhombic shape together, resulting in a stitched section being formed between each adjacent two net members. Also, the net includes a slide fastener including a slider with a lug and arranged at one of the stitched section and covers arranged at the portion of the one stitched section at which the slide fastener is positioned when the slide fastener is closed. The slider and lug are covered with the overlap portion between the covers. Such construction of the laundry net not only permits water to constantly flow into the net body and through the interior of the net body irrespective of its position with respect to the flow of water in the wash tub of the washing machine, so that the washing in the net body may be positively contacted with the flowing water but effectively prevents the slider and lug from damaging washing outside the laundry net.
