Abstract
The present application provides a light-emitting device, a display apparatus, the light-emitting device including: a substrate; at least two light-emitting units, in a direction perpendicular to the plane where the substrate is located, orthographic projections of two adjacent light-emitting units on the substrate overlap; at least one patterned bonding layer, located between two adjacent light-emitting units, including a plurality of spaced bonding portions, the bonding portions are configured to be fixed and electrically connected to the two adjacent light-emitting units; the orthographic projection of the bonding portion on the substrate is within the orthographic projection of the light-emitting unit on the substrate, and the sum of the orthographic projection areas of all bonding portions on the substrate is less than the area of the orthographic projection of the light-emitting device on the substrate. Embodiments of the present application provide a light-emitting device with high luminous efficiency and preferable wavelength uniformity.
