Method of fabricating light-emitting element
A method of fabricating a light-emitting element, in which less stress is applied to the light-emitting element, includes: forming element isolation patterns on a substrate; forming a buffer layer on an entire surface of the substrate to directly contact the surface of the substrate and the element isolation patterns and forming light-emitting structure layers on the buffer layer; forming element isolation trenches, which overlap at least part of the element isolation patterns, respectively, buffer layer patterns and light-emitting structures which are separated from each other by the element isolation trenches, respectively, by etching the buffer layer and the light-emitting structure layers; injecting a lift-off solution into the element isolation trenches to remove the element isolation patterns; and removing the substrate.
