description A display panel includes: a light emitting layer each having a light emitting region defined thereon; an organic encapsulation layer disposed on the light emitting layer and providing a planarized upper surface; an inorganic encapsulation layer disposed on the upper surface of the organic encapsulation layer and having a first refractive index; a functional layer disposed on the inorganic encapsulation layer and having a second refractive index lower than the first refractive index; and a partition barrier rib disposed on the functional layer and having an opening corresponding to the light emitting region defined. A total reflection critical angle between the inorganic encapsulation layer and the functional layer may be smaller than a reference incident angle of reference light traveling from the light emitting region toward the partition wall. 표시 패널은 각각이 발광 영역이 정의된 발광층, 상기 발광층 위에 배치되며 평탄화된 상면을 제공하는 유기 봉지층, 상기 유기 봉지층의 상기 상면 위에 배치되며 제1 굴절률을 갖는 무기 봉지층, 상기 무기 봉지층 위에 배치되며 상기 제1 굴절률보다 낮은 제2 굴절률을 갖는 기능층, 및 상기 기능층 위에 배치되며 발광 영역에 대응하는 개구부가 정의된 분할 격벽을 포함할 수 있다. 상기 무기 봉지층과 상기 기능층 사이의 전반사 임계각은 상기 발광 영역으로부터 상기 분할 격벽을 향해 진행하는 기준광의 기준 입사각보다 작을 수 있다.
