An in-plane switching mode liquid crystal display device includes: a gate line on a substrate along a first direction; a data line crossing the gate line along a second direction to define a pixel region; a gate electrode connected to the gate line; a semiconductor layer over the gate electrode; a source electrode and a drain electrode spaced apart from each other on the semiconductor layer; a common line spaced apart from the gate line and disposed along the first direction; a common electrode connected to the common line, the common electrode having a first common electrode pattern and a second common electrode pattern extending from the first common electrode pattern in the pixel region; an auxiliary common electrode extending from the common line, the auxiliary common electrode having a first protrusion pattern overlapping with an end portion of the second common electrode pattern, the first protrusion in parallel with the second common electrode pattern; a pixel electrode connected to the drain electrode, the pixel electrode having a first pixel electrode pattern and a second pixel electrode pattern extending from the first pixel electrode pattern in the pixel region; and an auxiliary pixel electrode extending from the drain electrode, the auxiliary pixel electrode having a second protrusion pattern overlapping an end portion of the second pixel electrode pattern, the second protrusion pattern in parallel with the second pixel electrode pattern.
