摘要：
A light-emitting element includes a monolithic understructure including a first surface and a second surface different from the first surface; a plurality of light-emitting structure units disposed on the second surface; and a trench formed on a portion of the first surface and between the plurality of light-emitting structure units, wherein a height of the portion of the first surface is greater than a height of the second surface measured from a bottom of the monolithic understructure, and the portion of the first surface is exposed by the trench.
