Light-emitting device having an optical resonance layer

摘要

Provided is a light-emitting device which has a simple structure and can be manufactured in a simple process, has increased light coupling efficiency and brightness, and can reduce adverse effects of optical resonance on a view angle and emission spectrum. The light-emitting device includes a substrate; a light-emitting diode formed on the substrate; and an optical resonance layer formed outside the light-emitting diode that induces resonance of light emitted from the light-emitting diode.
