Abstract

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.

Description

technical field [0001] The invention relates to a display substrate. More particularly, the present invention relates to a display substrate, a method of manufacturing the display substrate, and a display device having the display substrate. Background technique [0002] A display substrate method of manufacturing a liquid crystal display (LCD) panel includes a rubbing process of forming a texture extending in a predetermined direction on an alignment film. The rubbing process can result in the discharge of static electricity on the display device. For example, rubbing a negatively charged cloth on a positively charged display substrate can result in an electrostatic discharge that damages the display device. Accordingly, defects due to electrostatic discharge may occur in the display substrate mainly where the metal thin film formed on the display substrate is exposed. Therefore, a method of manufacturing a display substrate has included forming a guard ring at an edge o...
