Patent ID: 7859623

Claim:
A liquid crystal display device comprising: a color filter substrate that includes a first polarizer, an optical compensation layer formed of a reactive mesogen, a first compensation film as an A-plate, a first substrate and a color filter array wherein the color filter array includes a black matrix disposed on the first substrate to divide a cell area; a plurality of color filters disposed in the cell area that is divided by the black matrix; and a common electrode disposed on the color filter to form a vertical electric field together with the pixel electrode; a thin film transistor substrate that includes a thin film transistor array, a second substrate, the thin film transistor array being disposed on the second substrate, a second polarizer disposed at a rear of the second substrate, and a second compensation film disposed between the second polarizer and the second substrate; wherein the thin film transistor array includes a gate line disposed on the second substrate; a data line that crosses the gate line to be insulated therefrom, thereby determining a pixel area; a thin film transistor disposed at a crossing part of the gate line and the data line; and a pixel electrode that is connected to the thin film transistor and disposed in the pixel area; wherein the optical compensation layer is disposed at a place between the color filter and the common electrode; wherein the light axis of the first compensation film has the same horizontal axis as the light transmission axis of the first polarizer.
