摘要： Disclosed are a micro LED and a display module including same, the micro LED comprising: a light-emitting surface; and a first electrode and a second electrode arranged on a surface opposite to the light-emitting surface. The disclosed micro LED comprises: a current diffusion layer to which the first electrode is electrically connected, and which has the light-emitting surface; a first cladding layer and a second cladding layer that are stacked on the current diffusion layer; an active layer arranged between the first cladding layer and the second cladding layer; and a current guiding unit arranged between the second electrode and the second cladding layer, and formed from a side surface of the micro LED to a position adjacent to the central part of the micro LED so that current flows while spaced from the side surface of the micro LED.
