Light emitting device and led display apparatus including the same

A display apparatus comprising:

• a display substrate;
• light emitting devices arranged on an upper surface of the display substrate, one or more the light emitting devices 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;
• and
• a second bonding layer coupling the second LED unit to the third LED unit;
• a light blocking structure located adjacent to and extending 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 LED units are coupled side by side in a horizontal direction with respect 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.
