Abstract

An IPS-LCD having a compensation electrode structure. In each pixel area, at least two common electrodes extending in a first Y-direction and at least one pixel electrode extending in a second Y-direction are inter-digitated with each other. Also, at least two compensation electrodes extending in the Y-direction are patterned on the same plane with the pixel electrode, and overlap the two common electrodes, respectively. A first interval between the first compensation electrode and pixel electrode is equal to a second interval between the pixel electrode and the second compensation electrode.
