Abstract

A display panel including a base layer; a circuit layer; an emission layer including first, second and third emission areas respectively corresponding to first, second and third pixel areas; an organic encapsulation layer having a flat top surface; an inorganic encapsulation layer on the top surface of the organic encapsulation layer and having a first refractive index; a functional layer disposed on the inorganic encapsulation aver and having a second refractive index less than the first refractive index; and a partition wall disposed on the functional layer and including first, second and third openings, wherein the first, second and third openings respectively correspond to the first, second and third pixel areas, wherein a total reflection critical angle between the inorganic encapsulation layer and the functional layer is less than a reference incident angle of reference light traveling from the first emission area toward the partition wall.
