1. A display apparatus comprising:
a lower substrate;
a display element layer above the lower substrate, wherein the display element layer comprises first to third display elements;
an encapsulation layer on the display element layer;
partition walls on the encapsulation layer to define first to third color regions, wherein the first to third color regions overlap the first to third display elements, respectively, in a view in a direction perpendicular to the lower substrate;
a quantum dot layer comprising a second color quantum dot layer in the second color region and a third color quantum dot layer in the third color region;
a reflective plate covering at least part of a surface of the partition walls, and
an insulating layer on the partition walls and the quantum dot layer,
wherein the reflective plate has a first surface and a second surface opposite to the first surface, the first surface is directly attached to the partition walls and the second surface is directly attached to the insulating layer.
