Patent ID: 7990486

Claim:
A liquid crystal display panel, comprising: a plurality of gate lines that are parallel to each other; a plurality of data lines that are parallel to each other and cross the gate lines; a plurality of pixel regions, each pixel region surrounded by two corresponding gate lines and two corresponding data lines, and each pixel region comprising a pixel electrode; and a plurality of common lines, wherein each common line comprises a common bus line and a plurality of sub common lines, the common bus line is parallel to the gate lines and disposed adjacent to a corresponding gate line, and the sub common lines perpendicularly extend from the common bus line; wherein the sub common lines define a plurality of rectangular ring-shaped repair lines extending along the data lines, the repair lines and the data lines are formed on different planes of the liquid crystal display panel, each repair line is provided at a respective one of the pixel regions and defined by each two adjacent sub common lines, the two adjacent sub common lines contact each other at two positions to define two opposite short sides of the repair line, one position is at front ends of the two adjacent sub common lines and adjacent to a corresponding common bus line, the other position is at tail ends of the two adjacent sub common lines and adjacent to a next gate line, the two short sides cross a corresponding data line and the repair line is electrically isolated from the corresponding data line.
