Abstract

Provided are a light-emitting device having improved light dispersion efficiency, a light-emitting system including the same, and fabricating methods of the light-emitting device and the light-emitting system. The light-emitting device includes one or more light-emitting elements arranged on first surface of a substrate, an insulation film formed on the first surface of a substrate so as to cover the one or more light-emitting elements, and a plurality of uneven patterns formed on the insulation film formed on each of the one or more light-emitting elements so as to be spaced apart from each other, wherein the plurality of uneven patterns are all convex patterns or concave patterns and each of the plurality of uneven patterns has a curved cross-sectional shape.
