Claim 14:
15. A display device comprising:
a first substrate;
a first electrode disposed on the first substrate;
an emission layer disposed on the first electrode;
a second electrode disposed on the emission layer;
a high refractive index member disposed on the second electrode, overlapping the emission layer, and having a refractive index between 1.5 and 1.6;
a low refractive index member disposed between the high refractive index member and the emission layer and having a refractive index between 1 and 1.4; and
a second substrate overlapping at least a portion of the first substrate, disposed on the high refractive index member, and having a refractive index between 1.5 and 1.6,
wherein the high refractive index member includes a first surface contacting the second substrate, a second surface opposite to the first surface and having a second length smaller than a first length of the first surface, and a side surface connecting the first substrate and the second substrate, and
wherein the side surface has an angle between 60 degrees and 75 degrees with respect to the first surface,
the high refractive index member has a closed shape, and
the low refractive index member and the second substrate entirely cover the closed shape of the high refractive member.
