Abstract
The present disclosure provides a light-emitting device having a patterned interface composed of a plurality of predetermined patterned structures mutually distinct, wherein the plurality of predetermined patterned structures are repeatedly arranged in the patterned interface such that any two neighboring patterned structures are different from each other. The present disclosure also provides a manufacturing method of the light-emitting device. The method comprises the steps of providing a substrate, generating a random pattern arrangement by a computing simulation, forming a mask having the random pattern arrangement on the substrate, and removing a portion of the substrate thereby transferring the random pattern arrangement to the substrate.
