Beschreibung
Zusammenfassung:	Provided is a display device, which includes: a light source supplying a first light; a color filter including a plurality of quantum dots which absorbs a first light and emits at least one of second light and third light that are different from the first light; a first optical filter layer disposed on the color filter, and blocking at least a part of the first light; and a second optical filter layer disposed between the light source and the color filter, and transmitting at least a part of the first light and reflecting at least a part of the second light and the third light. The present invention provides the display device with improved light efficiency and viewing angle compared to power consumption. 제1광을 공급하는 광원, 제1광을 흡수하여 제1광과 다른 제2광 및 제3광 중 적어도 하나를 방출하는 복수의 양자점을 포함하는 컬러 필터, 컬러 필터 상에 배치되고, 제1광의 적어도 일부를 차단하는 제1 광학 필터층 및 광원과 상기 컬러 필터 사이에 배치되고, 제1광의 적어도 일부는 투과시키고, 제2광 및 제3광의 적어도 일부는 반사시키는 제2 광학 필터층을 포함하는 표시 장치가 제공된다.
