Title:
LIGHT-EMITTING ELEMENT, DISPLAY DEVICE, AND METHOD FOR FORMING LIGHT-EMITTING LAYER
Document Type and Number:
WIPO Patent Application WO/2024/075248
Kind Code:
A1
Abstract:
This light-emitting element (1) comprises an anode (22), a cathode (25), and a light-emitting layer (8) provided between the anode (22) and the cathode (25). The light-emitting layer (8) includes a first part (8a) including an inorganic matrix of a first material, and a second part (b) including an inorganic matrix of a second material. The first part (8a) is provided closer to the anode (22) than the second part (8b). The first part (8a) includes a plurality of quantum dots (QD) having a third material different from the first material and the second material, at least the inorganic matrix of the first material is filled between the plurality of quantum dots (QD), and the filling rate of the quantum dots (QD) in the cross section of the first part (8a) is greater than the filling rate of the quantum dots (QD) in the cross section of the second part (8b).
