  • Patent number: 7843520
    Abstract: A display apparatus includes a plurality of pixel regions. Each of the pixel regions includes a first sub-pixel region, a second sub-pixel region and a boost capacitor. The first sub-pixel region and the second sub-pixel region are electrically connected to the boost capacitor. The boost capacitor causes voltages the first and second sub-pixel regions to be at different voltages to increase the viewing angle of the display apparatus. One electrode of the boost capacitor, a coupling electrode, is formed over a storage capacitance line made of an opaque metal such that an additional boost capacitor (Cboost) may be formed without decreasing the aperture ratio of the pixel region. Other features are also provided.

  • Publication number: 20100157177
    Abstract: A display apparatus includes a display panel, a first polarization part, and a second polarization part. The display panel includes an array substrate, an opposite substrate and an electro-optical material layer disposed between the array substrate and the opposite substrate. The electro-optical material layer reflects first circularly polarized light having a wavelength of a predetermined range and transmits second circularly polarized light having a phase difference with the first circularly polarized light. The first polarization part faces a rear face of the array substrate and converts incident light of the rear face into the first circularly polarized light. The second polarization part faces a front face of the opposite substrate and blocks the first circularly polarized light reflected from the electro-optical material layer and transmits the second circularly polarized light transmitted through the electro-optical material layer.
