Patent ID: 8064018

Claim:
A liquid crystal display device comprising: a vertical alignment liquid crystal layer; a first substrate and a second substrate, which face each other with the liquid crystal layer interposed between them; and at least one alignment film, which is arranged in contact with the liquid crystal layer, wherein the first substrate includes a TFT, a gate bus line, a source bus line and a storage capacitor line, and wherein each pixel region includes two subpixel regions, in which mutually different voltages are applied to the liquid crystal layer with respect to a signal voltage that has been supplied from the source bus line by way of their associated TFTs, and wherein the first substrate further includes a first electrode, which is provided for each of the two subpixel regions, and wherein the second substrate includes a second electrode, which is arranged so as to face the first electrode with the liquid crystal layer interposed between them, and wherein a liquid crystal capacitor, formed by the first and second electrodes and the liquid crystal layer between the first and second electrodes, is provided for each said subpixel region, and wherein each said subpixel region includes at least one liquid crystal domain that produces a dark area, which looks darker than a gray scale tone being presented for a viewer located in front of the device, inside of, and substantially parallel to, an edge portion of the first electrode, and wherein at least a part of the edge portion of the first electrode is arranged so as to overlap with the gate bus line and selectively shield at least a part of the dark area from incoming light, and wherein two TFTs associated with the two subpixel regions have substantially equal drain-gate capacitances Cgd, and wherein the gate electrodes and/or drain electrodes of the first and second transistors have mutually different areas, respectively.
