A method of fabricating a light emitting element, the method comprising:

• sequentially forming a first semiconductor layer, a light emitting layer, and a second semiconductor layer on a substrate;
• sequentially forming a mask layer and an etch pattern on the second semiconductor layer;
• patterning, in a rod shape, a stack structure including the first semiconductor layer, the light emitting layer, and the second semiconductor layer through an etching process using the mask layer and the etch pattern;
• forming an electrode layer on the second semiconductor layer;
• forming an insulative film on side surfaces of the first semiconductor layer, the light emitting layer, the second semiconductor layer, and the electrode layer;
• and
• separating, from the substrate, a light emitting element including the stack structure and the insulative film provided on a side surface of the stack structure,
• wherein, in the forming of the electrode layer, the electrode layer is etched such that the side surface of the electrode layer has a slope corresponding to an angle in a range of about 90 degrees to about 135 degrees with the substrate.
