Patent ID: 7206051

Claim:
An in-plane switching mode LCD device comprising: a first substrate; one or more gate line arranged in a first direction on the first substrate; one or more data line arranged in a second direction perpendicular to the first direction on the first substrate, a crossing of the one or more data line with the one or more gate line defining a pixel region; a common electrode module disposed in the pixel region; a pixel electrode module disposed in the pixel region, overlapping the common electrode module; a second substrate facing the first substrate; a first alignment film and a second alignment film disposed at facing surfaces of the first and second substrates, respectively; and a liquid crystal layer between the first alignment film and the second alignment film, wherein the common electrode module includes a plurality of common electrodes arranged parallel to the one or more gate line, a left common electrode auxiliary line disposed at an outer left edge of the pixel region, and a right common electrode auxiliary line disposed at an outer right edge of the pixel region, the left and the right common electrode auxiliary lines connecting the plurality of common electrodes, and wherein the pixel electrode module includes a plurality of pixel electrodes arranged parallel to the one or more data line, and an upper pixel electrode auxiliary line disposed at an upper most end of the pixel region and connecting the pixel electrodes, the plurality of pixel electrodes crossing the plurality of common electrodes to define a plurality of sub-pixel regions.
