Abstract:
1. An array substrate for a liquid crystal display device, comprising: a gate line and a data line on a substrate, the data line crossing the gate line to define a pixel region; an insulating layer between the gate line and the data line; a switching element adjacent to a crossing of the gate line and the data line; a pixel electrode connected to the switching element, the pixel electrode disposed in the pixel region; a first buffer pattern at a first side of the gate line and overlapped with the date line, the first buffer pattern being disposed at the same layer as the gate line, wherein the first buffer pattern has a bar shape parallel to and is spaced apart from the gate line, wherein an overlapped portion between the first buffer pattern and the data line has bilateral symmetry, and wherein the first buffer pattern is spaced apart from the pixel electrode in a horizontal plane; and a second buffer pattern at a second side of the gate line opposite to the first side and overlapped with the data line, wherein the second buffer pattern extends from the gate line.
