Display device equipped with touch sensor

Abstract

Disclosed is a display device that has a light detecting element (D) disposed in a pixel region (), an opening (a through hole) () formed in an insulating film () that is disposed above the light detecting element (D), and a transparent electrode () formed in the opening (), and that can reduce occurrence of leakage between the transparent electrode () and other wiring line (SL). Specifically disclosed is a display device that has an active matrix substrate () in which a first wiring line (SL) and a second wiring line (GL) are formed so as to cross each other, and a light detecting element (D) disposed on a pixel region () in the active matrix substrate (). The display device has a first insulating film () formed between the first wiring line (SL) and the second wiring line (GL), a second insulating film (19) disposed on the first insulating film (), and a transparent electrode () formed above the light detecting element (D) so as to enter a through hole () formed in the second insulating film (). The first wiring line (SL) has a discontinuous section at a part adjacent to the light detecting element, and both ends of the discontinuous section are electrically connected to each other through an auxiliary wiring line () disposed in the same layer as that of the second wiring line (GL).
