1. A display apparatus comprising:
a display element disposed on a substrate and comprising an emission area;
a thin-film encapsulation layer disposed on the display element, the thin-film encapsulation layer comprising:
at least one inorganic encapsulation layer; and
at least one organic encapsulation layer;
a first insulating layer disposed on the thin-film encapsulation layer, the first insulating layer comprising:
an opening that corresponds to the emission area; and
a refraction area defined by the opening and comprising an organic material; and
a second insulating layer disposed on the first insulating layer, filling the refraction area, and having a refractive index greater than a refractive index of the first insulating layer, wherein
the display element comprises a first display element and a second display element,
the refraction area has a circular shape, a polygonal shape having eight or more sides, or an elliptical shape in a plan view,
the refraction area comprising:
a first refraction area corresponding to the first display element; and
a second refraction area corresponding to the second display element,
the first refraction area and the second refraction area are different in at least one of a relative size to a corresponding emission area, a shape, and an arrangement,
a first emission area overlaps the first refraction area and the first display element in a plan view and
a first distance in a plan view between an end of the first refraction area and an end of the first emission area corresponding to a first side of the first emission area is different from a second distance in a plan view between an end of the first refraction area and an end of the first emission area corresponding to second and different side of the first emission area.
