Abstract
A display apparatus includes a driving substrate, a plurality of micro light-emitting devices, and a common electrode. The micro light-emitting devices are separately arranged on the driving substrate, and each of the micro light-emitting devices includes an epitaxial structure, a first type electrode, and a second type electrode. The first type electrode and the second type electrode are disposed on opposite surfaces of the epitaxial structure. The common electrode is disposed on the driving substrate and located between the second type electrodes of the micro light-emitting devices, and the common electrode exposes an upper surface of each of the second type electrodes.
