Patent ID: 8059223

Claim:
A data line repair structure for a liquid crystal display panel comprising a scan line, a data line crossing the scan line, a thin film transistor formed where the scan line crosses the data line and connected to a pixel electrode, a gate driving chip electrical connected to the scan line to generate a gate signal to drive the thin film transistor, and a source driving chip connected to the data line to provide a data signal to the pixel electrode, the data line repair structure comprising: a first repair line parallel to the scan line and crossing a first end of the data line; a fourth repair line formed in an oblique line area of the liquid crystal panel, coupled to the first repair line; a second repair line parallel to the data line, coupled to the gate driving chip and the fourth repair line; a third repair line parallel to the scan line, coupled to the second repair line and separated from a second end of the data line; and a floating line connected between the third repair line and the second end of the data line when the data line has a broken point.
