Zusammenfassung:A light emitting display device according to the present specification comprises: a substrate comprising a plurality of pixels having a light emitting area and a light exit surface; a pixel circuit layer comprising a plurality of insulating layers disposed on top of the substrate; a protective layer disposed on top of the pixel circuit layer; a light extraction part disposed on top of the protective layer of the light emitting area and comprising a plurality of concave parts and a convex part between the plurality of concave parts; a light emitting element layer disposed on the light extraction part and configured so as to emit light to the light exit surface; and a plurality of insulating layers disposed on each of a plurality of pixels and a light guide surface formed on any one among the protective layers, wherein the light guide surface overlaps the light emitting area and is inclined with respect to the light exit surface. Therefore, the present invention is capable of improving light extraction efficiency. 본 명세서에 따른 발광 표시 장치는 발광 영역을 갖는 복수의 화소와 광 출사면을 포함하는 기판, 기판 위에 배치된 복수의 절연층을 포함하는 화소 회로층, 화소 회로층 위에 배치된 보호층, 발광 영역의 보호층 위에 배치되고 복수의 오목부와 복수의 오목부 사이의 볼록부를 포함하는 광 추출부, 광 추출부 상에 배치되고 광 출사면으로 광을 방출하도록 구성된 발광 소자층, 및 복수의 화소 각각에 배치된 복수의 절연층 및 상기 보호층 중 어느 하나에 형성된 광 가이드면을 포함하며, 광 가이드면은 발광 영역과 중첩되고 광 출사면에 대해 경사진다.
