Abstract: A liquid crystal display includes at least one pixel. The pixel includes a first sub-pixel charged with a first voltage and a second sub-pixel charged with a second voltage different from the first voltage. A first sub-pixel electrode provided in the first sub-pixel and a second sub-pixel electrode provided in the second sub-pixel include slits having different widths according to directions. Due to the slits, average directors of the first and second sub-pixels are tilted in a horizontal or vertical direction. Accordingly, a side visibility of the display apparatus is improved.
