Abstract:
1. An array substrate for a liquid crystal display device, comprising: a substrate; first and second gate lines along a first direction on the substrate; first, second and third data lines along a second direction and crossing the first and second gate lines to define first and second pixel regions; first and second thin film transistors at a crossing portion of the second gate line and the first data line and at a crossing portion of the second gate line and the second data line, respectively; first and second pixel electrodes in the first and second pixel regions, respectively, the first pixel electrode connected to the first thin film transistor and the second pixel electrode connected to the second thin film transistor; and first and second common lines between the first and second gate lines, the first and second common lines overlapping the first and second pixel electrodes, respectively, and connected to each other under the second data line without a gap therebetween to cover a part of the second data line between the first and second gate lines, wherein the first and second common lines each have two sides extending from the first and second common lines and parallel to the second direction, respectively, and an entire side of the first common line directly contacts an entire side of the second common line, wherein the sides of the first and second common lines directly contacting each other have a same length as a maximum length of the first and second common lines along the second direction, wherein a channel between source and drain electrodes of each of the first and second thin film transistors has an angle larger than 0 degree and smaller than 90 degrees with respect to the first direction, wherein each of the first common line and the second common line includes a horizontal portion, a first vertical portion, and a second vertical portion, the horizontal portion disposed along the first direction, the first and second vertical portions extending from the horizontal portion along the second direction, wherein the first vertical portion has two ends along the second direction, and the second vertical portion has two ends along the second direction, wherein a first distance from one end of the first vertical portion to a connecting portion between the first vertical portion and the horizontal portion is shorter than a second distance from the other end of the first vertical portion to the connecting portion between the first vertical portion and the horizontal portion, wherein a third distance from one end of the second vertical portion to a connecting portion between the second vertical portion and the horizontal portion is longer than a fourth distance from the other end of the second vertical portion to the connecting portion between the second vertical portion and the horizontal portion.
