Abstract
A micro light emitting device display apparatus including a circuit substrate, a plurality of epitaxial structures, a plurality of contact pads and a plurality of light shielding patterns is provided. The plurality of epitaxial structures are dispersedly arranged on the circuit substrate. The plurality of contact pads are disposed between the plurality of epitaxial structures and the circuit substrate. The plurality of epitaxial structures are electrically connected to the circuit substrate via the plurality of contact pads respectively. The plurality of light shielding patterns and the plurality of contact pads are alternately arranged on the circuit substrate, and each of the light shielding patterns is connected between two adjacent contact pads without overlapping with the contact pads and is adapted to block light with a wavelength ranging from 150 nm to 400 nm from penetrating through. A method of fabricating the micro light emitting device display apparatus is also provided.
