Patent ID: 8071984

Claim:
A thin film transistor substrate for a display device having a plurality of thin film transistors and pixel electrodes connected to the thin film transistors, said thin film transistor substrate comprising: a plurality of pad electrodes in a non-display area of the display device for applying signals to the plurality of thin film transistors in a non-display area of the display device, wherein the plurality of pad electrodes are formed on a lower substrate of the thin film transistor substrate; a protective film covering the pad electrodes in the non-display area; and a slit in the protective film to infiltrate a stripper adjacent to at least one of the plurality of pad electrodes, wherein the slit is between two of the plurality of pad electrodes in the non-display area, and wherein a transparent conductive pattern is formed on side walls of the slit, and is directly formed on the lower substrate exposed through the slit.
