1. A display panel comprising:
a substrate comprising a first display area and a second display area surrounded by the first display area;
an insulating layer including an organic insulating material;
a plurality of first light-emitting elements in the first display area;
a plurality of second light-emitting elements in the second display area, the plurality of second light-emitting elements comprising light-emitting elements that are spaced apart from one another to define transmission areas; and
a photorefractive portion in each of the transmission areas,
wherein the photorefractive portion comprises:
a first surface facing the substrate; and
a second surface opposite the first surface,
wherein a distance between the substrate and a central portion of the second surface is greater than a distance between the substrate and an edge of the second surface,
wherein the photorefractive portion is spaced apart from each of the light-emitting elements of the plurality of second light-emitting elements, and
wherein the distance between the substrate and the central portion of the second surface is less than a distance between the substrate and a pixel electrode of an adjacent light-emitting element from among the plurality of second light-emitting elements.
