Abstract
A light emitting diode display includes a driving substrate, a plurality of micro light-emitting devices, a first common electrode, and a second common electrode. The micro light-emitting devices are arranged on the driving substrate. Each of the micro light-emitting devices includes an epitaxial structure, a first type electrode, and a second type electrode. The first common electrode is disposed on the driving substrate and located between the second type electrodes of the micro light-emitting devices, wherein the first common electrode exposes at least a portion of an upper surface of each of the second type electrodes. The second common electrode is located between the second type electrodes of the micro light-emitting devices and electrically connected to the first common electrode, wherein the second common electrode does not directly contact the micro light-emitting devices.
