Patent ID: 8259244

Claim:
A thin film transistor substrate comprising a plurality of pixels arrayed in a matrix and having: a gate line extending in a first direction; a data line intersecting the gate line in a second direction; a plurality of thin film transistors each comprising a gate electrode, a source electrode, and a drain electrode; and a pixel electrode electrically connected to the drain electrode, wherein a first thin film transistor of an upper pixel is located on a first side with respect to the data line, the first thin film transistor including a first source electrode disposed on the first side with respect to the data line, and a second thin film transistor of a lower pixel neighboring the upper pixel and located on a second side with respect to the data line is located on the second side with respect to the data line, and the data line has protruding patterns near the first and second thin film transistors, respectively, the protruding patterns including a first protruding pattern disposed closer to the first thin film transistor than to the second thin film transistor, the first protruding pattern protruding on the second side with respect to the data line.
