Abstract
Provided are a micro LED and a method for manufacturing the same. When the micro LED is manufactured, an n-electrode and a protective layer formed on the micro LED is made of a variable resistance material that is a transparent material, and a voltage greater than a unique threshold voltage of the variable resistance material is applied to the variable resistance material on an area of the protective layer formed on the p-type semiconductor layer to form a conductive filament in the variable resistance material, thereby forming a transparent electrode. Thus, the micro LED according to the present invention may be produced with lower cost and higher productivity by omitting the mask process for forming the transparent electrode in the prior art.
