Patent ID: 7956945

Claim:
An array substrate for a liquid crystal display device, comprising: a substrate having a display region and a non-display region at a periphery of the display region; a gate line, a data line, a thin film transistor and a pixel electrode on the substrate and in the display region; a drive integrated circuit on the substrate and in the non-display region; first and second test pads at both sides of the drive integrated circuit, respectively; a common voltage line on the substrate and along edges of the non-display region; and first and second static electricity protecting units on the substrate and in the display region, the first static electricity protecting unit connecting the first test pad with the common voltage line, and the second static electricity protecting unit connecting the second test pad with the common voltage line, wherein the first static electricity protecting unit includes a semiconductor pattern, a first discharging line and a second discharging line respectively disposed at both sides of the semiconductor pattern, and a connection pattern, wherein the semiconductor pattern is disposed on the gate insulating layer on the common voltage line and positioned between the common voltage line and the first test pad, wherein portions of the first and second discharging lines overlap the semiconductor pattern and the second discharging line extends from the first test pad, and wherein the connection pattern connects the first discharging line with the common voltage line.
