1. A light emitting device for a display, comprising:
a transparent layer through which light can be transmitted, laterally extending in a first direction, and having a first region and a second region surrounding the first region;
a first light emission region disposed on the transparent layer;
a second light emission region disposed on the first light emission region;
a third light emission region disposed on the second light emission region;
a support substrate disposed on the first, second, and third light emission regions, the first, second, and third light emission regions being disposed between the support substrate and the transparent layer;
an insulator disposed between the transparent layer and the support substrate and including a plurality of via openings; and
a first electrode pad, a second electrode pad, a third electrode pad, and a fourth electrode pad electrically connected through the plurality of via openings to a respective one or more of the first, second, or third light emission regions,
wherein each of the first, second, and third light emission regions is disposed in the first region of the transparent layer and does not overlap the second region of the transparent layer in a second direction crossing the first direction,
wherein the fourth electrode pad overlaps some of the plurality of via openings and one of the first, second, and third light emission regions in the second direction, and the some of the plurality of via openings are separated from each other in the first direction,
wherein the insulator covers an outer side surface of the first light emission region, the second light emission region, and the third light emission region, and extends outwardly away from the outer side surface of the first light emission region, the second light emission region, and the third light emission region,
wherein an outer side surface of the insulator is disposed further away from the first light emission region than the outer side surface of the third light emission region when viewed from a top, and
wherein the insulator includes a distributed Bragg reflector (DBR) dielectric mirror.
