Abstract: A display device according to an aspect includes: an array substrate including a plurality of first light-transmitting electrodes each disposed in a corresponding one of pixels; a counter substrate including positions that overlap the first light-transmitting electrodes in a plan view and are provided with a second light-transmitting electrode; a liquid crystal layer including polymer-dispersed liquid crystals filled between the array substrate and the counter substrate; and at least one light emitter configured to emit light toward a side surface of the counter substrate. The array substrate includes, in each of the pixels, a third light-transmitting electrode and a conductive metal layer. The third light-transmitting electrode at least partially overlaps the first light-transmitting electrode in the plan view with an inorganic insulating layer interposed therebetween, and the conductive metal layer is stacked on the third light-transmitting electrode.
