Provided is a technique for reducing display defects caused by an electric field in a direction perpendicular to an in-plane-switching liquid crystal display panel without compromising the design properties of a display device equipped with a touch sensor, in which a touch sensor is formed in the display panel. A display device equipped with a touch sensor is provided with an active-matrix substrate 10b having pixel electrodes 18 and shared electrodes 19, a color filter substrate 10a, and a liquid crystal layer 10c driven by transverse electric fields generated between the pixel electrodes 18 and the shared electrodes 19. A touch sensor having a drive electrodes 11 and detection electrodes 12 arranged so as to be separated from each other in the horizontal direction is provided to the reverse side of the color filter substrate 10a from the active-matrix substrate 10b, and dummy electrodes 13 in an electrically floating state are provided between the drive electrodes 11 and the detection electrodes 12. A grounded shield electrode 10d is provided between the dummy electrodes 13 and the liquid crystal layer 10c. |
