LIGHT-EMITTING ELEMENT AND DISPLAY DEVICE

Title:

LIGHT-EMITTING ELEMENT AND DISPLAY DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/186846

Kind Code:

A1

Abstract:

This light-emitting element (50) comprises a light-emitting layer (54), a hole transport layer (55), and an electron transport layer (53). The light-emitting layer (54) includes a quantum dot dopant (61), and hosts (62) comprising a hole transport host (62A) and an electron transport host (62B). Exciton energy generated in the hosts (62) transfers to the quantum dot dopant (61), thereby causing the quantum dot dopant (61) to emit light.
