ABSTRACT:
An in-plane switching (IPS) mode liquid crystal display (LCD) includes: a plurality of gate lines and 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 and data lines and including an active layer, a source electrode and a drain electrode, respectively; a common electrode line substantially parallel to the gate 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 alternately disposed on upper and lower portions of the pixel regions to generate an in-plane electric field; and a second substrate attached with the first substrate.
