Abstract

A display device includes: a plurality of light-emitters including a first light-emitter in a first display area and a second light-emitter in a second display area, the first light-emitter and second light-emitter configured to emit light of a same color, the second display area having a higher light transmissivity than the first display area; an insulating layer including a first through-hole and a second through-hole; and a filter disposed on the plurality of light-emitters and including a light-shield and color filters. The first through-hole of the insulating layer overlaps the first electrode of the first light-emitter, and the second through-hole of the insulating layer overlaps the first electrode of the second light-emitter, and at least a portion of the second through-hole overlaps the light-shield.
