ABSTRACT:
A liquid crystal display is provided. Red, blue and green pixels are sequentially arranged in a row direction. The red pixels and the green pixels are alternately arranged in a column direction and the blue pixels are arranged in the column direction. Four red and green pixels surrounding adjacent two blue pixels in neighboring two pixel rows face each other. Pixel electrodes and a common electrode have cutouts. A ratio of horizontal to vertical of each pixel is equal to 2:3. In this structure, a PenTile Matrix driving provides high resolution images, and the control of the arrangement of the liquid crystal molecules by the cutouts of the pixel electrode and the common electrode and the common electrode provides wide viewing angle.
