Micro led and display module having same

A micro light emitting diode (LED) comprising:

• a current spreading layer comprising a light-emitting surface;
• a first electrode disposed on the light-emitting surface of the current spreading layer and electrically connected to the current spreading layer;
• a first cladding layer and a second cladding layer that are stacked on the current spreading layer;
• an active layer disposed between the first cladding layer and the second cladding layer;
• a second electrode;
• a current guiding part disposed between the second electrode and the second cladding layer, and positioned in a central part of the second cladding layer, the current guide part being configured to guiding a current to flow away from a side surface of the micro LED;
• and
• a passivation layer provided on the side surface of the micro LED,
• wherein the second electrode has a lateral length greater than a lateral length of an area of the current guiding part, through which the current passes.

A display module comprising:

• a thin film transistor (TFT) substrate comprising a glass substrate and a TFT layer provided on one surface of the glass substrate;
• and
• a plurality of TFT electrodes provided on the TFT layer;
• a plurality of micro light emitting diodes (LEDs) electrically connected to the plurality of TFT electrodes,
• wherein each of the micro LEDs comprises:
