1. A display apparatus comprising:

  • a display panel disposed between a first polarizer and a second polarizer, a first light-transmission axis direction of the first polarizer being substantially perpendicular to a second light-transmission axis direction of the second polarizer, the first light-transmission axis direction intersecting a horizontal axis direction by approximately 45 degrees, the display panel having at least one first area and at least one second area, the at least one first area and the at least one second area respectively having a plurality of pixel units arranged in arrays, a row direction of the pixel units being substantially parallel to the horizontal axis direction, each of the pixel units having;

    a first sub-pixel area comprising a first alignment area, a second alignment area, and a third alignment area, a first alignment direction of the first alignment area being substantially perpendicular to the horizontal axis direction; and

    a second sub-pixel area, the second sub-pixel area being a fourth alignment area, a fourth alignment direction of the fourth alignment area being opposite to the first alignment direction, whereinwhen the display panel is in a narrow viewing angle display mode, a driving voltage at the first sub-pixel areas in the at least one first area is substantially lower than a driving voltage at the second sub-pixel areas in the at least one first area and a driving voltage at the first sub-pixel areas in the at least one second area, and the driving voltage at the second sub-pixel areas in the at least one first area is substantially higher than the driving voltage at the first sub-pixel areas in the at least one second area and a driving voltage at the second sub-pixel areas in the at least one second area.
