Patent ID: 8174637

Claim:
A thin-film transistor substrate comprising: gate lines which extend in a first direction, the gate lines including a first gate line and a second gate line, the first gate line disposed adjacent to and previous to the second gate line; data lines which are insulated from the gate lines and extend in a second direction perpendicular to the first direction; a pixel electrode formed in a region where the first gate line and the second gate line cross the data lines and connected to the second gate line; and a repair pattern which at least partially overlaps the first gate line, the repair pattern comprising a plurality of connection patterns, wherein the connection patterns extend from the pixel electrode on a same layer in the second direction toward the first gate line, the connection patterns at least partially connect the pixel electrode directly to the first gate line when the pixel electrode exhibits a bright-spot defect, each of the connection patterns have a predetermined width measured in the first direction, and are arranged at predetermined intervals along the first direction.
