An FFS(Fringe-Field Switching) LCD(Liquid Crystal Display) capable of adjusting the viewing angle is provided to implement a wide viewing angle and a narrow viewing angle properly using a vertical electric field and a fringe electric field respectively for a pixel driving area and a viewing angle driving area in each pixel by arranging different electrodes at the pixel driving area and the viewing angle driving area. An FFS LCD comprises a lower substrate, the first common electrode(1), an insulating layer, the first pixel electrode(2), the second pixel electrode(3), a liquid crystal layer, an upper substrate, and the second common electrode(4). A transparent glass or plastic substrate is used as the lower substrate. The first common electrode is patterned on the lower substrate. The insulating layer is located between the upper part of the first common electrode and the first and second pixel electrodes. The first pixel electrode, a width of 1 to 5 micrometers, is patterned on a portion of the upper part of the insulating layer vertically in the form of a lattice. The second pixel electrode is pattern on the other portion of the upper part of the insulating layer. The liquid crystal layer is horizontally aligned on the first and second pixel electrodes. As the upper substrate, a transparent glass or plastic substrate is also used. Corresponding to the second pixel electrode patterned on the lower substrate, the second common electrode is patterned on the upper substrate. Two pairs of thin film transistors are formed as one gate electrode(6) is located between the first pixel electrode and the second pixel electrode and two signal lines are used. The liquid crystal of the liquid crustal layer has positive dielectric isotropy. |
