Abstract:
1. An in-plane switching mode liquid crystal display device comprising: a first substrate; a gate line disposed in a first direction on the first substrate; a data line disposed in a second direction on the first substrate, the data line crossing the gate line to define a pixel region; pixel electrodes and common electrodes disposed in the first direction in the pixel region, the pixel electrodes and the common electrodes generating an in-plane electric field within the pixel region, the pixel electrodes placed at an upper portion of the pixel region and a lower portion of the pixel region, the common electrodes placed at the upper portion of the pixel region and the lower portion of the pixel region; a first common line disposed parallel to the data line at left side of the pixel region; a second common line disposed parallel to the data line at right side of the pixel region; a first common electrode connection line connecting at least two common electrodes placed at the upper portion of the pixel region and forming a first common electrode overlapping region by overlapping the first common line; a second common electrode connection line connecting at least two other common electrodes placed at the lower portion of the pixel region and forming a second common electrode overlapping region by overlapping the second common line; a first pixel electrode connection line connecting at least two pixel electrodes placed at the upper portion of the pixel region and forming a first pixel electrode overlapping region by overlapping the first common line; and a second pixel electrode connection line connecting at least two other pixel electrodes placed at the lower portion of the pixel region and forming a second pixel electrode overlapping region by overlapping the second common line, wherein the first common electrode connection line is formed at left side of the upper portion of the pixel region, the second common electrode connection line is formed at right side of the lower portion of the pixel region, the first pixel electrode connection line is formed at right side of the upper portion of the pixel region, and the second pixel electrode connection line is formed at left side of the lower portion of the pixel region, wherein the first common electrode overlapping region and the second common electrode overlapping region have substantially the same size, and the first pixel electrode overlapping region and the second pixel electrode overlapping region have substantially the same size, wherein the first common electrode connection line, the second common electrode connection line, the first pixel electrode connection line and the second pixel electrode connection line are formed on the same layer, wherein one side of at least one of the common electrodes and the pixel electrodes is bent, wherein the first and second common lines are wider than the first and second common electrode connection line and the first and second pixel electrode connection line.
