Led display module, manufacturing method for led display module and display device including led display module

A method for manufacturing a display module, the method comprising:

• forming a plurality of light emitting diodes (LEDs);
• and
• forming a plurality of partition walls that divide light-emitting regions by each of the plurality of LEDs,
• wherein the forming the plurality of LEDs comprises:
• etching a growth substrate to form a plurality of LEDs and forming a plurality of protrusions and a plurality of depressions on the growth substrate;
• and
• forming a reflector layer on a surface of the plurality of protrusions and a surface of the plurality of depressions, and
• wherein the forming the plurality of partition walls comprises removing a part of the growth substrate so that the plurality of partition walls are formed based on the plurality of protrusions, and a space between the plurality of partition walls is formed based on the plurality of depressions.

A display device comprising:

• a plurality of display modules;
• and
• a support plate configured to support the plurality of display modules,
• wherein each of the plurality of display modules comprises:
• a plurality of light-emitting diodes (LEDs);
• a driving substrate;
• a driving circuit on an upper portion of the driving substrate and configured to drive the plurality of LEDs;
• a plurality of partition walls configured to divide light-emitting regions by each of the plurality of LEDs;
• and
• reflective layers formed on both sides of each of the plurality of partition walls.
