Patent ID: 8098340

Claim:
A display substrate, comprising: a substrate, including a TFT layer having first and second gate wirings and a data wiring crossing the first and second gate wirings; a pixel electrode patterned in the shape of a unit pixel area on the TFT layer, the pixel electrode including; a first sub electrode receiving a first pixel voltage from the TFT layer; and, a second sub electrode electrically separated from the first sub electrode and receiving a second pixel voltage from the TFT layer; first storage wiring formed between and substantially parallel with the first and second gate wirings in the unit pixel area and operative to maintain the first pixel voltage and configured to receive a maintaining voltage from an external device; a second storage wiring formed between and substantially parallel with the first and second gate wirings in the unit pixel area and operative to maintain the second pixel voltage and configured to receive the maintaining voltage from the external device independently of the first storage wiring; and a storage duplication wiring formed along edges of the unit pixel area and electrically connecting the first storage wiring to the second storage wiring, wherein the storage duplication wiring is at an oblique angle to the data wiring and is not overlapped with the first and second sub electrodes, and wherein the storage duplication wiring extends along a space between the first sub electrode of the unit pixel area and the second sub electrode of another unit pixel area adjacent to the unit pixel area.
