Abstract: A method of manufacturing a nano-scale LED electrode assembly including a selective metal ohmic layer is disclosed. Specifically, the method can be useful in increasing conductivity between a nano-scale LED device and electrodes and also reducing contact resistance therebetween by depositing a conductive material in a region in which the nano-scale LED device comes in contact with the electrodes so as to improve the contact between the nano-scale LED device and the electrodes, thereby further improving light extraction efficiency of the nano-scale LED device.
