Zusammenfassung:	A micro light-emitting device includes an epitaxial unit and a current-spreading layer. The epitaxial unit has a top portion that includes an ohmic contact region and a non-ohmic contact region. The top portion has a periphery area which forms at least a part of the non-ohmic contact region. The periphery area has a reduced conductivity compared with the remainder of the top portion. The current-spreading layer is disposed on the ohmic contact region. A method for making the micro light-emitting device, and a display screen including the same are also disclosed.
