1. A display comprising:
a substrate;
a plurality of diodes on the substrate;
an encapsulation layer covering the plurality of diodes;
a color filter layer on the encapsulation layer;
a first color conversion element disposed between the encapsulation layer and the color filter layer, the first color conversion element converting incident light into light of a first color;
a second color conversion element disposed between the encapsulation layer and the color filter layer, the second color conversion element converting incident light into light of a second color;
a refractive layer disposed between the color filter layer and the first and second color conversion elements, the refractive layer having a refractive index less than those of the first and second color conversion elements;
a first barrier layer disposed between the color filter layer and the first and second color conversion elements;
a black matrix disposed between the first color conversion element and the second color conversion element; and
a coating layer disposed between the refractive layer and the encapsulation layer.
