Abstract: The display device includes a display panel and a front surface panel that is superimposed with the display panel, and that is switched between a reflective state in which incident light is reflected and a transmissive state in which incident light is transmitted. The front surface panel can detect presence of an object to be detected.

Abstract: According to an aspect, a display device includes: a substrate having a display region; a shield conductive layer provided above the substrate; and a plurality of wiring units for temperature detection disposed at positions overlapping with the display region and the shield conductive layer when seen in a plan view. Each wiring unit for temperature detection has one end coupled to a first wire and the other end coupled to a second wire to detect resistance that changes in accordance with a change in temperature, between the first wire and the second wire.
