摘要： 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.
