Micro light emitting device display apparatus and method of fabricating the same

A method of fabricating a micro light emitting device display apparatus, comprising:

• forming an epitaxial layer on an epitaxial substrate, and forming a plurality of first sub-contact pads separated from each other on the epitaxial layer;
• forming a plurality of second sub-contact pads separated from each other on a circuit substrate;
• bonding the epitaxial substrate to the circuit substrate;
• electrically bonding the first sub-contact pads and the second sub-contact pads to form a plurality of contact pads electrically connected to the epitaxial layer and the circuit substrate;
• forming a plurality of light shielding patterns between the epitaxial substrate and the circuit substrate, wherein the light shielding patterns and the second sub-contact pads are alternately arranged on the circuit substrate, the light shielding patterns are not overlapped with the second sub-contact pads, and the light shielding patterns are capable of blocking light with a wavelength ranging from 150 mu to 400 nm from penetrating through;
• after the circuit substrate is bonded to the epitaxial substrate, removing the epitaxial substrate;
• and
• etching the epitaxial layer to form a plurality of epitaxial structures, wherein the epitaxial structures respectively correspond to the contact pads and are electrically connected to the circuit substrate via the contact pads respectively.
