  • Publication number: 20040222815
    Abstract: A method and apparatus for testing a liquid crystal display device are provided to detect a defect location precisely and rapidly without requiring a jig. The method includes providing a substrate to inspect, wherein the substrate includes signal wirings, drive switches and capacitors formed in an effective display area of the substrate; radiating a light onto an inspection switch device and thereby supplying an inspection voltage from an inspection line to one of the drive switches through the signal wirings, so as to charge one of the capacitors; and determining if there is a defect in the effective display area of the substrate by reading the charged voltage of the capacitor.

  • Publication number: 20040135947
    Abstract: A transflective LCD device includes first and second transparent substrates spaced apart from each other and having a reflective portion and a transmissive portion, an insulator on the first transparent substrate, a passivation layer on the insulator within the reflective portion, a reflector on the passivation layer, a transparent pixel electrode disposed over the insulator covering the reflector and the passivation layer, a buffer pattern disposed on a rear surface of the second substrate, the buffer pattern having a saw-tooth shape corresponding to the reflective portion, a color filter on the rear surface of the second substrate covering the buffer pattern, the color filter having a first thickness in the transmissive portion and a second thickness in the reflective portion, a transparent common electrode on a rear surface of the color filter, and a liquid crystal layer between the transparent pixel electrode and the transparent common electrode.

  • Publication number: 20040135149
    Abstract: A thin film transistor liquid crystal display is designed such that TFTs for driving green pixels are formed in the blue pixel regions. This improves the overall brightness of the liquid crystal display based on the human view-sensitive characteristics.
