Patent ID: 7907245

Claim:
An in-plane switching (IPS) mode liquid crystal display (LCD) device comprising: a plurality of gate lines and a plurality of data lines arranged vertically and horizontally to define a plurality of pixel regions on a first substrate; thin film transistors (TFTs) at each crossing of the gate lines and the data lines and including an active layer, a source electrode and a drain electrode, respectively; a plurality of common electrode lines arranged substantially parallel to the gate lines, wherein the plurality of common electrode lines are disposed at upper and lower portions of the pixel region, and wherein upper and lower common electrode lines are connected by branches substantially parallel to the data lines; a plurality of first pixel electrodes and first common electrodes and a plurality of second pixel electrodes and second common electrodes having a tilt angle with respect to the gate lines and arranged in an alternating pattern on upper and lower portions of the pixel regions to generate an in-plane electric field; a pixel electrode line electrically connected with the drain electrode via a first contact hole: a first connection line connecting the pixel electrode line and the first and second pixel electrodes; a second connection line connecting the plurality of common electrode lines and the first and second common electrodes, wherein the first and second connection lines overlap with the branches, respectively; and a second substrate attached with the first substrate.
