Patent ID: 8035788

Claim:
A liquid crystal display device, comprising: first and second substrates facing and spaced apart from each other, each of the first and second substrates having an image-displaying sub pixel and a viewing angle-adjusting sub pixel; a thin film transistor corresponding to each of the image-displaying sub pixel and the viewing angle-adjusting sub pixel; a liquid crystal display layer between the first and second substrates, the liquid crystal layer having a negative dielectric constant anisotropy; a pixel electrode in an entire area of each of the image-displaying sub pixel and the viewing angle-adjusting sub pixel on an inner surface of the first substrate; a common electrode on an entire inner surface of the second substrate; a first field distortion means in the image-displaying sub pixel, wherein the first field distortion means includes at least one having a circular shape to form a multi-domain in the image-displaying sub pixel, and wherein the first field distortion means includes at least one of a first common protrusion of a dielectric material on the common electrode and a first common slit in the common electrode; and a second field distortion means in the viewing angle-adjusting sub pixel, wherein the second field distortion means includes at least one having one of a horizontal bar shape and a vertical bar shape to form a two-domain in the viewing angle-adjusting sub pixel, and wherein the second field distortion means includes at least one of a second common protrusion of a dielectric material on the common electrode and a second common slit in the common electrode.
