    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.
