Patent ID: 8628368

Claim:
A method of fabricating a light-emitting device, the method comprising: providing one or more light-emitting elements on a first surface of a substrate; forming an insulation film on the first surface of a substrate, the insulation film covering the one or more light-emitting elements; and forming a plurality of first uneven patterns on the insulation film and over each of the one or more light-emitting elements, the plurality of first uneven patterns being spaced apart from each other, wherein forming the plurality of first uneven patterns includes: forming a photoresist film on the insulation film, compressing a substrate including a plurality of imprinted second uneven patterns on the photoresist film, compressing forming a plurality of third uneven patterns in complement with the plurality of imprinted second uneven patterns onto the photoresist film, and processing the photoresist film to form the plurality of first uneven patterns based on the third uneven patterns, wherein the plurality of first uneven patterns are all convex patterns or all concave patterns and each of the plurality of first uneven patterns has a curved cross-sectional shape.
