Publication number: 20080204618Abstract: A display substrate includes a substrate, a guard ring and a connecting line. The substrate includes a plurality of active areas, and each of the active areas has a pixel area and a peripheral area. The guard ring is formed on the substrate to enclose each of the active areas, and is formed from substantially the same layer as a pixel electrode that is formed in a unit pixel. The connecting line is formed from a different layer than the guard ring, to electrically connect the guard ring with pads. The connecting line is formed before forming an organic insulating layer, and thus the frequency and/or severity of patterning defects of the connecting line may be reduced or prevented. Accordingly, short circuits between the pads may be prevented, and the corrosion resistance of the display apparatus may be increased.Type: ApplicationFiled: February 20, 2008Publication date: August 28, 2008Inventors: Min-Kyung JUNG, Yong-Han Park, Hyung-Don Na, Hyun-Young Kim
