Claim 15:
16. A display panel, comprising:
a display substrate including a display area, a non-display area, a fiat top surface overlapping the display area and an emission layer configured to provide source light;
a functional layer having a second refractive index less than a first refractive index of an uppermost layer of the display substrate forming the flat top surface;
a first light conversion pattern disposed on the functional layer to convert the source light into first color light;
a second light conversion pattern disposed on the functional layer to convert the source light into second color light; and
an optical pattern disposed on the functional layer to transmit the source light therethrough,
wherein a total reflection critical angle between the uppermost layer and the functional layer is less than a reference incident angle of reference light that travels from an area of the emission layer overlapping the first light conversion pattern toward the second light conversion pattern or the optical pattern.
