A liquid crystal display device includes pixel electrodes, a common electrode placed in such a manner that at least part thereof overlaps the pixel electrodes via an inter-transparent-electrode-film insulating film, at least two source lines, placed in such a manner that the pixel electrodes are interposed therebetween, that supply the pixel electrodes with image signals, and a common electrode wire, placed in such a manner that the pixel electrodes that are adjacent to the two source lines between which the pixel electrodes are interposed between the common electrode wire and the source lines, that extends parallel to the source lines and supplies the common electrode with at least a reference potential signal.
