Zusammenfassung:	The present invention relates to a display device and a manufacturing method therefor, the display device comprising: a lower substrate including a transistor and a light source; and an upper substrate including a cover substrate, a black matrix layer, a reflective layer, a light conversion layer, and a planarization layer, wherein the reflective layer comprises a particular component such as a titanium oxide, and the cross-section of the reflective layer cut in the direction perpendicular to the longitudinal direction has a reverse taper shape, and thus the light efficiency of quantum dots that omnidirectionally emit light can be improved and the overflow of ink, occurring in the discharge step of an inkjet process, can be prevented. La présente invention concerne un dispositif d'affichage et un procédé de fabrication associé, le dispositif d'affichage comprenant : un substrat inférieur comprenant un transistor et une source de lumière ; et un substrat supérieur comprenant un substrat de recouvrement, une couche de matrice noire, une couche réfléchissante, une couche de conversion de lumière et une couche de planarisation, la couche réfléchissante comprenant un constituant particulier tel qu'un oxyde de titane et la section transversale de la couche réfléchissante découpée dans la direction perpendiculaire à la direction longitudinale ayant une forme de conicité inverse, ce qui permet d'améliorer l'efficacité lumineuse de points quantiques qui émettent de la lumière de manière omnidirectionnelle et d'éviter le phénomène de trop-plein d'encre qui se produit au cours de l'étape de décharge d'un procédé à jet d'encre. 본 발명은 표시장치 및 이의 제조방법에 관한 것으로서, 트랜지스터 및 광원을 포함하는 하부 기판과 커버 기판, 블랙 매트릭스층, 반사층, 광변환층 및 평탄화층을 포함하며, 상기 반사층이 산화 티탄 등과 같은 특정 성분을 포함하고, 길이 방향에 대한 수직 방향으로 절단한 반사층의 단면이 역테이퍼(reverse taper)의 형상인 상부 기판을 포함함으로써, 전 방향으로 발광하는 양자 점의 광효율을 향상시킬 수 있고, 잉크젯 공정의 토출 과정에서 발생하는 잉크의 넘침을 방지할 수 있는 표시장치 및 이의 제조방법에 관한 것이다.
