Display device using semiconductor light-emitting diodes, and method for manufacturing same

A display device comprising:

• a substrate;
• semiconductor light-emitting diodes disposed on the substrate;
• a planarization layer formed to cover the semiconductor light-emitting diodes;
• and
• a wiring electrode electrically connected to the semiconductor light-emitting diodes,
• wherein the substrate comprises individual pixel regions in which the semiconductor light-emitting diodes are disposed, and
• wherein the individual pixel regions comprises:
• a first individual pixel region in which the semiconductor light-emitting diodes are disposed to emit light output from the semiconductor light-emitting diodes;
• and
• a second individual pixel region in which a repair layer is disposed to emit light output from the first individual pixel region adjacent thereto, and
• wherein the repair layer is formed of a material having a smaller refractive index than a material of the planarization layer.
