Abstract: To provide a display device with excellent display quality, in a display device including a signal line, a scan line, a transistor, a pixel electrode, and a common electrode in a pixel, the common electrode is included in which an extending direction of a region overlapping with the signal line differs from an extending direction of a region overlapping with the pixel electrode in a planar shape and the extending directions intersect with each other between the signal line and the pixel electrode. Thus, a change in transmittance of the pixel can be suppressed; accordingly, flickers can be reduced.
