Display device and manufacturing method thereof

A method of manufacturing a display apparatus, comprising:

• forming a light emitting diode chip on a manufacturing substrate;
• forming a protector to cover light emitting diode chip;
• irradiating the light emitting diode chip with a laser to separate the light emitting diode chip from the manufacturing substrate;
• removing the protector;
• and
• transferring the light emitting diode chip from the manufacturing substrate to another substrate,
• wherein the light emitting diode chip comprises:
• a light emitting structure including a first conductivity type semiconductor layer, a second conductivity type semiconductor layer, and an active layer interposed between the first and second conductivity type semiconductor layers;
• a second electrode electrically connected to the second conductivity type semiconductor layer;
• an insulator disposed to cover a portion of an upper surface of the second electrode and side surfaces of the light emitting structure;
• and
• a second coupler covering an upper portion of the insulator, and electrically connected to the second electrode, at least a portion of the second coupler extending to the side surfaces of the light emitting structure.
