Summary:A display device is provided. The display device comprises: a substrate which includes a display area having a plurality of light-emitting areas and a light-blocking area, and a non-display area surrounding the display area; a thin-film transistor layer which is disposed on the substrate and includes a plurality of thin-film transistors; a light-emitting element layer which is disposed on the thin-film transistor layer and includes a plurality of light-emitting elements; a wavelength conversion layer which is disposed on the light-emitting element layer and converts the peak wavelength of light provided by at least some of the plurality of light-emitting elements; and a color filter layer which is disposed on the wavelength conversion layer, wherein the color filter layer comprises: a plurality of color filters disposed in the plurality of light-emitting areas respectively; a first light-blocking member disposed in the light-blocking area; and a second light-blocking member disposed in the non-display area. L'invention concerne un dispositif d'affichage. Le dispositif d'affichage comprend : un substrat qui comprend une zone d'affichage comportant une pluralité de zones électroluminescentes et une zone de blocage de lumière, et une zone de non-affichage entourant la zone d'affichage ; une couche de transistors à couches minces disposée sur le substrat et comprenant une pluralité de transistors à couches minces ; une couche d'éléments électroluminescents disposée sur la couche de transistors à couches minces et comprenant une pluralité d'éléments électroluminescents ; une couche de conversion de longueur d'onde disposée sur la couche d'éléments électroluminescents et convertissant la longueur d'onde de crête de la lumière fournie par au moins certains éléments de la pluralité d'éléments électroluminescents ; et une couche de filtres colorés disposée sur la couche de conversion de longueur d'onde, la couche de filtres colorés comprenant : une pluralité de filtres colorés disposés respectivement dans les zones de la pluralité de zones électroluminescentes ; un premier élément de blocage de lumière disposé dans la zone de blocage de lumière ; et un second élément de blocage de lumière disposé dans la zone de non-affichage. 표시 장치가 제공된다. 표시 장치는 복수의 발광 영역 및 차광 영역을 구비한 표시 영역, 및 상기 표시 영역을 둘러싸는 비표시 영역을 포함하는 기판, 상기 기판 상에 배치되고 복수의 박막 트랜지스터를 포함하는 박막 트랜지스터층, 상기 박막 트랜지스터층 상에 배치되고 복수의 발광 소자를 포함하는 발광 소자층, 상기 발광 소자층 상에 배치되어 상기 복수의 발광 소자 중 적어도 일부의 발광 소자에서 제공된 광의 피크 파장을 변환시키는 파장 변환층, 및 상기 파장 변환층 상에 배치된 컬러 필터층을 포함하고, 상기 컬러 필터층은 상기 복수의 발광 영역 각각에 배치된 복수의 컬러 필터, 상기 차광 영역에 배치된 제1 차광 부재, 및 상기 비표시 영역에 배치된 제2 차광 부재를 포함한다.
