Abstract:
1. A method of driving a liquid crystal display device, comprising: displaying an image by applying an image voltage to a first electrode group in image drive areas; and adjusting a viewing angle by applying a viewing angle control voltage to a second electrode group in viewing angle control areas, wherein the liquid crystal display device comprises: a plurality of pixels, each pixel having a plurality of sub-pixels for displaying an image, each of the viewing angle control areas being one of the sub-pixels in each pixel that controls the viewing angle of the liquid crystal display device, wherein the viewing angle control areas are located between the image drive areas, a first black matrix surrounding each of the sub-pixels; and a second black matrix in a central area of each of the viewing angle control areas for preventing light leakage in the viewing angle control areas, wherein the second black matrix does not extend from or contact the first black matrix.
