Beschreibung
Zusammenfassung:In the composite sheet, a second color conversion layer is composited on a first color conversion layer, the first color conversion layer comprises green quantum dots or a combination of green quantum dots and red quantum dots, and the second color conversion layer comprises a red organic nano-phosphor. The color reproducibility of the display device can be improved without reducing brightness and reliability. 本发明的复合片在第一颜色转换层复合第二颜色转换层，上述第一颜色转换层包括绿色量子点或绿色量子点和红色量子点的组合，上述第二颜色转换层包括红色有机纳米荧光体，由此，可在不降低亮度和可靠性的情况下提高显示装置的颜色再现性。
