Abstract

A display device includes a first translucent substrate, a second translucent substrate that is disposed on a display surface side while opposed to the first translucent substrate, and a first light reduction unit that reduces a transmission amount of visible light while overlapping a bright point defect portion in planar view in at least one of the first translucent substrate and the second translucent substrate. The first light reduction unit has a circular shape including a first region disposed in a center and a second region disposed around the first region, and transmittance to the visible light in the first region is higher than transmittance to the visible light in the second region.
