1. A display device, comprising:
a backplane;
a first light emitting diode (LED) containing a first reflector and configured to emit first color light bonded to the backplane;
a second LED containing a second reflector and configured to emit second color light different from the first color light bonded to the backplane; and
a third LED containing a third reflector and configured to emit third color light different from the first and second color light bonded to the backplane;
wherein the second reflector is thicker than the first reflector, and the third reflector is thicker than the second reflector, and
wherein each of the first LED, the second LED and the third LED is provided on a planar top surface of the backplane.
