According to one embodiment, a liquid crystal display device includes a first common electrode including a first sub-common electrode extending along a gate line on a first interlayer insulation film, a pixel electrode which includes a first main pixel electrode extending in a second direction on a second interlayer insulation film, 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 is located on the pixel electrode side of a position overlapping the gate line. The second sub-common electrode is opposed to the gate line.
