Patent ID: 7375786

Claim:
A liquid crystal display device comprising: a substrate; a gate line formed over the substrate and extending in a first direction; a first insulating film formed over the gate line and the substrate; a data line formed over the first insulating film and extending in a second direction; a thin film transistor electrically connected to the gate line and the data line, and comprising a semiconductor region formed over the first insulating film; a second insulating film formed over the data line, the semiconductor region, and the first insulating film; a pixel electrode formed over the second insulating film, and electrically connected to the thin film transistor in a first opening formed through the second insulating film; a gate terminal connecting to the gate line; and a drain terminal connected to the data line, wherein the drain terminal comprises an ITO layer connected to the data line in a second opening formed through the second insulating film, and the ITO layer comprises a first edge extending in the first direction and disposed between the second opening and the gate line, and a first portion disposed between the second opening and an edge of the substrate that is parallel with the gate line and disposed at a side with respect to the second opening which is opposite to the gate line with respect to a side of the second opening, and a second edge and a third edge extending in the second direction, and wherein a distance from the second opening to the first portion is longer than a distance from the second opening to the second edge, and the distance from the second opening to the first portion is longer than a distance from the second opening to the third edge.
