Document Type and Number:
WIPO Patent Application WO/2017/140047
Kind Code:
A1
Abstract:
A light-emitting device, a preparation method therefor and a display apparatus. In the light-emitting device (01), a light-emitting functional layer (30) comprises at least two quantum dot light-emitting layers (31) capable of emitting light of different colours, and a transparent insulating layer (32) located between any two adjacent quantum dot light-emitting layers (31). The light-emitting device (01) has reduced energy consumption, and overcomes the problem of light-emitting colour cast caused by the transmission of high-energy excitons.
