Abstract
The present invention relates to a substrate for changing the color of a light emitting diode and a method for producing same and, more particularly, to a substrate for changing the color of a light emitting diode and a method for producing same, wherein the substrate may be hermetically sealed so that quantum dots (QD) contained inside may be completely protected from the outside and emission efficiency of the light emitting diode may be enhanced.
