  • Patent number: 8023073
    Abstract: A liquid crystal display (“LCD”) includes forming only a ?/4 plate between a polarizer and a display panel and setting a direction of an absorption axis of the polarizer and a slow axis of the ?/4 plate, so that the LCD can have a smaller thickness and its fabrication cost can be reduced while having better or the same characteristics than an LCD using both ?/2 and ?/4 plates. In addition, in an ECB mode backlit LCD, transmittance, contrast ratio, and viewing angles can be enhanced by attaching both the ?/4 or ?/2 plate and allowing the absorption axis of the polarizer and the slow axis of the ?/4 and ?/2 plates to have predetermined angle relationships.

  • Patent number: 7940363
    Abstract: A liquid crystal display (LCD) panel includes first and second substrates, and a liquid crystal layer interposed between the first and second substrates. The first substrate includes gate lines, data lines, a storage line and a pixel electrode. The gate lines extend along a first direction. The data lines extend along a second direction crossing the first direction, and the gate and data lines define a unit pixel. The storage line includes a first line portion extending along the second direction in the unit pixel. The pixel electrode divides the unit pixel into first and second domains. A second substrate faces the first substrate and includes a common electrode having a first hole formed on the common electrode, and the first hole is overlapped with the storage line. The first hole and the storage line are overlapped with each other, so that an opening ratio may be enhanced.
