Abstract:
1. A liquid crystal display device, which comprises: a plurality of pixel units arranged in a matrix form, wherein each of the pixel units further comprises: a first sub-pixel electrode, which is set at a central position of the pixel unit; and a second sub-pixel electrode, which is circumferentially set along a circumference of the first sub-pixel electrode; wherein an area of the first sub-pixel electrode and an area of the second sub-pixel electrode are of a ratio of 1:2, a drive voltage of a liquid crystal layer corresponding to the first sub-pixel electrode being a first drive voltage, a drive voltage of a liquid crystal layer corresponding to the second sub-pixel electrode being a second drive voltage, the first drive voltage being less than the second drive voltage; and wherein the second sub-pixel electrode comprises an outer circumference that is rectangular and an inner circumference that is rectangular and defines a rectangular hollow area, the first sub-pixel electrode having an outer circumference that is rectangular and substantially corresponds in shape and size to the rectangular hollow area of the second sub-pixel electrode so as to be received in the rectangular hollow area.
