In a liquid crystal display device, a first interlayer insulating film is arranged on a gate line and first, second and third source lines. A first common electrode includes a first sub-common electrode on the first interlayer insulating film and facing the gate line. A second insulating film covers the first common electrode. A first main pixel electrode extends on the second interlayer insulating film between the first source line and the second source line. A second main pixel electrode extends on the second interlayer insulating film between the second source line and the third source line. A second common electrode includes a second sub-common electrode extending on the second interlayer insulating film between the first source line and the second source line so as to face the first sub-common electrode, and is cut out between the second source line and the third source line.
