Zusammenfassung:	According to the present invention, provided is a composite sheet. A second color conversion layer including a green organic nanophosphor is combined with a first color conversion layer including green quantum dots or a combination of green quantum dots and red quantum dots, so that color reproducibility of the display device can be improved without deterioration of luminance and reliability. 본 발명에 따른 복합 시트는 녹색 양자점 또는 녹색 양자점과 적색 양자점의 조합을 포함하는 제 1 색변환층에 녹색 유기 나노형광체를 포함하는 제 2 색변환층이 복합됨으로써, 휘도와 신뢰성의 저하 없이 디스플레이 장치의 색재현성을 향상시킬 수 있다.
