ABSTRACT:
An in plane switching liquid crystal display (2) includes a first substrate (27), a second substrate (37) and a liquid crystal layer (23) having a plurality of liquid crystal molecules. A number of pixel electrodes (25) and common electrodes (24) are formed on the first substrate, and each of the pixel electrodes and common electrodes include at least two bend portions (241, 242, 243). Each bend portion has a first side and a second side. An original alignment direction of the liquid crystal molecules form at least two different angles with the sides of the bend portions of the common and pixel electrodes. When a voltage is applied to the pixel electrodes and the common electrodes, the liquid crystal molecules are aligned along at least three different directions. Therefore, the IPS-LCD can have uniform viewing performance at different viewing angles.
