Provided is a method of manufacturing a light-emitting diode (LED) package. The method includes: preparing a support structure on which a plurality of LED chips, each of which includes a semiconductor stack structure, and a light-transmissive material layer covering the plurality of LED chips are formed; mounting the support structure, on which the LED chips and the light-transmissive material layer are formed, on a cutting stage; and cutting the light-transmissive material layer, the semiconductor stack structure, and the support structure between the plurality of LED chips, by using a cutting device having a pattern blade on the cutting stage to singulate each of the individual LED packages.
