1. A light-emitting device comprising:
- a substrate;
a light-emitting diode arranged on the substrate;
an interlayer arranged between the substrate and the light-emitting diode; and
an optical resonance layer consisting of a first layer and a second layer arranged between the light-emitting diode and the substrate,wherein an uppermost surface of the first layer directly contacts the interlayer, a lowermost surface of the second layer directly contacts the substrate, and a lowermost surface of the first layer directly contacts an uppermost surface of the second layer, the optical resonance layer to induce resonance of light emitted from the light-emitting diode, andwherein a refractive index of the second layer is higher than that of the first layer.

Abstract
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.
