Abstract:
1. A liquid crystal display device, comprising: a gate line and a data line crossing each other to define a pixel region on a substrate; a thin film transistor connected to the gate and data lines and including a gate electrode extending from the gate line, a semiconductor layer over the gate electrode, source and drain electrode on the semiconductor layer and spaced apart from each other, the source electrode extending from the data line; a pixel electrode in the pixel region and including a first pixel portion which has a plurality of bent portions and first and second pixel protrusion portions protruding from the bent portions alternately in an opposing direction; and a common electrode in the pixel region and including first to third common portions, a plurality of first common protrusion portions extending from the first common portion toward the second common portion, a plurality of second common protrusion portions extending from the second common portion toward the first common portion, a plurality of third common protrusion portions extending from the first common portion toward the third common portion, and a plurality of fourth common protrusion portions extending from the third common portion toward the first common portion, wherein the first and second pixel protrusion portions are substantially parallel to the gate line, and the first common portion is positioned between the second and third common portions, wherein the first common protrusion portions are alternately arranged with the second common protrusion portions, and the third common protrusion portions are alternately arranged with the fourth common protrusion portions, and wherein at least one of the second and fourth common protrusion portions is spaced apart from the first common portion.
