1. A display device comprising:
a first substrate comprising an array of pixels, a pixel of the array of pixels comprising an electrode in the first substrate;
a second substrate coupled to the first substrate; and
a sealing member between the first substrate and the second substrate,
wherein the second substrate comprises:
a base substrate comprising a display area overlapping the array of pixels and a peripheral area around the display area;
a first compensation structure in the peripheral area, on the base substrate, at least partially overlapping the sealing member, and comprising an organic material;
a second compensation structure in the peripheral area, on the base substrate, spaced apart from the first compensation structure, at least partially overlapping the sealing member, and comprising the same material as that of the first compensation structure; and
a first capping layer covering the first and second compensation structures and comprising an inorganic material,
wherein the first compensation structure is around the display area,
wherein the second compensation structure is around the first compensation structure, and
wherein the first capping layer covers a lower surface of the first compensation structure facing the first substrate, a lower surface of the second compensation structure facing the first substrate, an outer side surface of the first compensation structure, and an inner side surface of the second compensation structure.
