1. A display device comprising:
a substrate;
a plurality of light-emitters on the substrate, the 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 being configured to emit light of a same color, wherein the second display area comprises a light transmission area having a higher light transmissivity than the first display area without including a pixel circuit;
an insulating layer including a first through-hole and a second through-hole, the first through-hole of the insulating layer overlapping a first electrode of the first light-emitter, and the second through-hole of the insulating layer overlapping a first electrode of the second light-emitter;
an inorganic insulating layer between the substrate and the first electrode of the second light-emitter, the inorganic insulating layer including a through-hole overlapping the light transmission area; and
a filter disposed on the plurality of light-emitters and including a light-shield and color filters,
wherein at least a portion of the second through-hole overlaps the light-shield, and
wherein the light-shield has a first-second opening overlapping with the second light-emitter in the second display area and a second-second opening overlapping with another second light-emitter in the second display area, the first-second opening having a different size from that of the second-second opening, and the second light-emitter and the other second light emitter of the second display area being configured to emit light of the same color as each other.
 
6. A display device comprising:
a substrate;
a plurality of light-emitters on the substrate, the plurality of light-emitters disposed in a display area including a first display area and a second display area, wherein the second display area comprises a light transmission area which does not include a pixel;
an insulating layer including a plurality of through-holes overlapping first electrodes of the plurality of light-emitters;
an inorganic insulating layer between the substrate and the first electrodes of the plurality of light-emitters, the inorganic insulating layer including a through-hole overlapping the light transmission area;
a light-shield disposed on the plurality of light-emitters and including a plurality of openings, the plurality of openings defining pixels and overlapping at least one of the plurality of through-holes of the insulating layer; and
color filters disposed in the plurality of openings of the light-shield,
wherein the at least one of the plurality of through-holes of the insulating layer overlaps the light-shield, and
wherein a first opening of the plurality of openings in the light-shield overlaps with a first-second light-emitter of the plurality of light-emitters in the second display area and a second opening of the plurality of openings overlaps with a second-second light-emitter of the plurality of light-emitters in the second display area, the first opening having a different size from that of the second opening, and the first-second light-emitter and the second-second light-emitter being configured to emit light of a same color as each other.
 
13. An electronic apparatus comprising:
a display device including a first display area and a second display area, wherein the second display area comprises a light transmission area having a higher transmissivity than the first display area without including a pixel circuit; and
a component overlapping the light transmission area in the second display area, wherein
the display device comprises:
a substrate;
a plurality of light-emitters on the substrate;
an insulating layer comprising a plurality of through-holes, the plurality of through-holes overlapping first electrodes of the plurality of light-emitters;
an inorganic insulating layer between the substrate and the first electrodes of the plurality of light-emitters, the inorganic insulating layer including a through-hole overlapping the light transmission area;
a light-shield disposed on the plurality of light-emitters and including a plurality of openings, the plurality of openings defining pixels and overlapping at least one of the plurality of through-holes of the insulating layer; and
color filters disposed in the plurality of openings of the light-shield,
wherein at least one of the plurality of through-holes of the insulating layer overlaps the light-shield, and
wherein a first opening of the plurality of openings in the light-shield overlaps with a first-second light-emitter of the plurality of light-emitters in the second display area and a second opening of the plurality of openings overlaps with a second-second light-emitter of the plurality of light-emitters in the second display area, the first opening having a different size from that of the second opening, and the first-second light-emitter and the second-second light-emitter being configured to emit light of a same color as each other.
