  • Patent number: 7626677
    Abstract: A liquid crystal display apparatus includes a first protective layer, a first polarizing layer, a second protective layer, an active device array substrate, an opposite substrate, a twisted nematic liquid crystal layer, a third protective layer, a second polarizing layer and a fourth protective layer. The first polarizing layer is disposed between the first and the second protective layers; the active device array substrate is disposed over the second protective layer. The twisted nematic liquid crystal layer is disposed between the opposite substrate and the active device array substrate. The third protective layer is disposed on the opposite substrate, and the second polarizing layer is disposed between the third and the fourth protective layers. The second protective layer has an in-plane and an out-of-plane retardation values. The in-plane retardation value is between 1 and 10 nanometers, and the out-of-plane retardation value is between 50 and 130 nanometers.

  • Patent number: 6956631
    Abstract: The present invention relates to a liquid crystal display device, which comprises a top polarizer and a lower polarizer, a liquid crystal cell, and a back light assemble, the device is characterized in that the lower polarizer is subjected to an anti-glaring treatment while the top polarizer is not. In the liquid crystal display device (LCD) according to the present invention, since the top polarizer is not subjected to the anti-glaring treatment, the prepared device exhibits a vision property similar to that of cathode ray tube (CRT) display device without brownish nor glittering problems associated with conventional LCD in which a top polarizer is subjected to anti-glaring treatment.
