Abstract
A micro light-emitting diode device includes a substrate, a micro light-emitting diode, a first protection layer and a second protection layer. The micro light-emitting diode is disposed on the substrate. The first protection layer is disposed on a first portion of an outer side wall of the micro light-emitting diode and has a gap from the substrate. The second protection layer is at least disposed on a second portion of the outer side wall and is located in the gap between the first protection layer and the substrate. A height of the second protection layer on the substrate is less than or equal to a height of the micro light-emitting diode on the substrate.
