1. A light emitting diode (LED) stack for a display, comprising:
a substrate;
a first LED stack disposed on the substrate;
a second LED stack disposed on the first LED stack;
a third LED stack disposed on the second LED stack;
a first color filter interposed between the first LED stack and the second LED stack; and
a second color filter interposed between the second LED stack and the third LED stack,
wherein the second LED stack and the third LED stack are configured to transmit light generated from the first LED stack to the outside,
wherein the third LED stack is configured to transmit light generated from the second LED stack to the outside, and
wherein the first color filter and the second color filter include insulation layers having different indices of refraction one above another.
