Abstract
A light-emitting structure includes: a first region and a second region, where the second region surrounds the first region; the first region includes a plurality of first light-emitting units, and the second region includes a plurality of second light-emitting units; and a distance between adjacent first light-emitting units is less than a distance between adjacent second light-emitting units in a circumferential direction or a radial direction of the light-emitting structure. The distance between the adjacent second light-emitting units of the second region arranged on the edge is large, which improves a doping rate of a light-emitting element in the second region, so that doping rates of the light-emitting element in the first region and the second region tend to be equal, thereby solving a problem of uneven light-emitting wavelengths in the first region and the second region when the light-emitting unit is prepared by epitaxy.
