Patent ID: 7636143

Claim:
An in-plane switching mode liquid crystal display (IPS-LCD) panel, comprising: a thin film transistor (TFT) substrate comprising: a plurality of gate lines that are parallel to each other and extend along a first direction; a plurality of source bus lines that are parallel to each other and extend along a second direction different from the first direction, the source bus lines crossing the gate lines to define a plurality of pixel regions, each of the pixel regions comprising: a pair of source bus lines; a pixel electrode that is between and parallel to the source bus lines; a pair of shield metal lines positioned at two opposite sides of the pixel electrode respectively; and a pair of common electrodes that are parallel to the pixel electrode and partly overlap the shield metal lines respectively, one of the common electrodes being positioned between the pixel electrode and one of the source bus lines, the other common electrode being positioned between the pixel electrode and the other source bus line, each of the common electrodes comprising a slit parallel with the corresponding source bus line and between the source bus line and the pixel electrode in order to attenuate any crosstalk between the source bus line and the pixel electrode, each of the common electrodes further comprising a first common electrode strip and a second common electrode strip at opposite sides of the slit respectively, the first common electrode strip being closer to the corresponding source bus line than the second common electrode strip; a color filter substrate facing the TFT substrate; and a liquid crystal layer sandwiched between the two substrates.
