Abstract: A light-emitting device includes a first electrode; a second electrode; N light-emitting units stacked between the first electrode and the second electrode; and a connection layer disposed between any two adjacent light-emitting units. A peak of an intrinsic spectrum of at least part of light-emitting units is in a range from 400 nm to 480 nm. A sum of peaks of intrinsic spectra of the N light-emitting units is in a range from N×400 nm to N×480 nm; N≥2, and N is a positive integer. A difference between a color coordinate y value of the light-emitting device under a blue image at a preset viewing angle that is in a range from 60° to 75° and a color coordinate y value of the light-emitting device under the blue image at a viewing angle of 0° is in a range from 0 to 0.07.

Abstract: Provided are a display panel and a manufacturing method thereof and a display device. The display panel includes: a base substrate; a pixel defining layer including first openings defining sub-pixels; an encapsulation layer; and a light modulation layer. The light modulation layer is configured such that light from each of at least one sub-pixel propagates along a direction away from the base substrate after total reflection upon incidence on an interface between the first light modulation portion in a corresponding second opening and the first light modulation sub-layer. The display panel satisfies at least one of a first condition or a second condition. The first condition is that at least a part of edge of the first orthographic projection has a recess. The second condition is that at least a part of edge of the second orthogonal projection has at least one of a recess or a protrusion.

Abstract: A display back panel may include a substrate, an insulating layer disposed on one side of the substrate and including a plurality of recesses, the plurality of recesses including a bottom surface, a first electrode disposed on a surface of the insulating layer away from the substrate, a pixel defining layer disposed on a surface of the first electrode away from the substrate and including a plurality of openings, a light-emitting layer disposed in the plurality of openings and covering the first electrode, and a second electrode disposed on a surface of the light-emitting layer away from the substrate. Therein, the first electrode may reflect waveguide light laterally propagated by the light-emitting layer, thereby improving a light-emitting efficiency of the light-emitting layer. Further, the reflected waveguide light may not be absorbed by the second electrode, thereby enhancing an external quantum effect of the light-emitting layer.
