Title:
LIGHT-EMITTING DEVICE AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/225782
Kind Code:
A1
Abstract:
The present application provides a light-emitting device and a display apparatus. The light-emitting device comprises: a substrate; at least two light-emitting units, orthographic projections of two adjacent light-emitting units on the substrate being overlapped along a direction perpendicular to a plane where the substrate is located; and at least one patterned bonding layer located between the two adjacent light-emitting units and comprising a plurality of bonding portions arranged at intervals, the bonding portions being fixed and electrically connected to the two adjacent light-emitting units, wherein orthographic projections of the bonding portions on the substrate are located within orthographic projections of the light-emitting units on the substrate, and a sum of areas of the orthographic projections of all the bonding portions on the substrate is smaller than the area of an orthographic projection of a light-exiting surface of the light-emitting device on the substrate. The light-emitting device provided by embodiments of the present application has high light-emitting efficiency and good wavelength uniformity.
