Abstract:
1. A liquid crystal display device comprising: a first substrate including a gate line extending in a first direction, a source line extending in a second direction crossing the first direction, a switching element electrically connected to the gate line and the source line, a first interlayer insulation film located above the gate line and the source line, a first common electrode including a first sub-common electrode extending along the gate line on the first interlayer insulation film, a second interlayer insulation film covering the first common electrode, a pixel electrode which includes a first main pixel electrode extending in the second direction on the second interlayer insulation film and is electrically connected to the switching element, and a second common electrode which includes a second sub-common electrode extending in parallel to the first sub-common electrode on the second interlayer insulation film and has the same potential as the first common electrode, the first sub-common electrode being located on the pixel electrode side of a position overlapping the gate line, and the second sub-common electrode being opposed to the gate line; a second substrate including a third common electrode which includes a third main common electrode extending in the second direction and a third sub-common electrode opposed to the second sub-common electrode, the third common electrode having the same potential as the second common electrode; and a liquid crystal layer held between the first substrate and the second substrate.
