Claim 15:
16. A light emitting device comprising:
a first LED unit comprising a first light emitting stack;
a second LED unit comprising a second light emitting stack;
a third LED unit comprising a third light emitting stack;
a first bonding layer coupling the first LED unit to the second LED unit;
a second bonding layer coupling the second LED unit to the third LED unit;
a first electrode electrically connected to the first LED unit;
a second electrode electrically connected to the second LED unit;
a third electrode electrically connected to the third LED unit;
a common electrode electrically connected to the first to third LED units, wherein the second electrode is electrically connected to the second LED unit on one side surface of the second LED unit;
a light blocking structure formed of a black material, wherein the light blocking structure is located adjacent to and extends along aligned surfaces of each of the first, second, and third LED units; and
a light transparent layer configured to transmit light emitted by the first, second, and third LED units,
wherein the first, the second and the third light emitting stacks are disposed perpendicular to an upper surface of the light transparent layer, and
wherein the first and second bonding layers include a non-conductive material that transmits light.
