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.
