Claim:
1. A liquid crystal display device, comprising: a first substrate including: first and second gate lines respectively extending in a first direction, first and second source lines respectively extending in a second direction crossing the first direction, a first interlayer insulating film arranged on the first and second gate lines, and the first and second source lines, a first common electrode including a first sub-common electrode and a second sub-common electrode extending in the first direction on the first interlayer insulating film, the first sub-common electrode overlapping with the first gate line and the second sub-common electrode overlapping with the second gate line, a second interlayer insulating film covering the first common electrode, a pixel electrode including a first main pixel electrode extending in the second direction on the second interlayer insulating film, the first main pixel electrode including a first end portion on a side of the first gate line and a second end portion on a side of the second gate line, and a second common electrode set to a same potential as the first common electrode and including a third sub-common electrode and a fourth sub-common electrode extending in the first direction on the second interlayer insulating film, wherein the third sub-common electrode overlaps with the first sub-common electrode, and includes a cut out portion on a straight line along which the first main pixel electrode extends, in a circumference of the first end portion of the first main pixel electrode, and the fourth sub-common electrode overlaps with the second sub-common electrode, and includes a cut out portion on the straight line along which the first main pixel electrode extends, in a circumference of the second end portion of the first main pixel electrode, a second substrate arranged facing the first substrate; and a liquid crystal layer held between the first substrate and the second substrate, wherein the cut out portion of the third sub-common electrode overlaps with the first gate line, and the cut out portion of the fourth sub-common electrode overlaps with the second gate line.
