Abstract
A micro device includes an epitaxial structure, an overcoat layer, and a first light-guiding structure. The epitaxial structure has a top surface and a bottom surface opposite to each other and a peripheral surface connecting the top surface and the bottom surface. The insulating layer covers at least the bottom surface and part of the peripheral surface of the epitaxial structure. The overcoat layer includes a contact portion and an extension portion. The contact portion conformally covers the insulating layer and the peripheral surface and the bottom surface of the epitaxial structure, and the extension portion connects the contact portion and extends in a direction away from the peripheral surface. The display apparatus includes a circuit substrate and a plurality of the above-mentioned micro devices. The micro devices are disposed and are correspondingly electrically connected to the first pads and the second pads of circuit substrate.
