Claim 0:
1. A light emitting apparatus, comprising:
a first LED sub-unit;
a second LED sub-unit disposed on the first LED sub-unit;
a third LED sub-unit disposed on the second LED sub-unit;
a plurality of connection electrodes electrically connected to at least one of the first, second, and third LED sub-units, the connection electrodes covering a side surface of at least one of the first, second, and third LED sub-units;
a first passivation layer surrounding side surfaces of at least one of the first, second, and third LED sub-units and including a region having a thickness greater than a thickness of each of the connection electrodes;
an insulating layer having first and second opposed surfaces, with the first surface facing the LED sub-units; and
