Abstract
An exemplary multi-domain vertical alignment LCD (200) includes a common electrode, a pixel electrode and a liquid crystal layer sandwiched between the common electrode and the pixel electrode. The LCD is regularly divided into a plurality of frist and second sub-pixel regions (250, 260). The first sub-pixel region corresponding to two of the first protrusions (241), one of the second protrusions (242), one of the first slits (281), and two of the second slits (282), a second sub-pixel region corresponding to two of the third protrusions (243), one of the fourth protrusions (244), one of the third slits (283), and two of the fourth slits (284), a first ratio of first distance between the first slit and the second slit to a first width of the first slit is less than second ratio of second distance between the third slit and the fourth slit to second width of the third slit.
