Accordingly, as a surface of the ultra-thin fin LED element, which is in contact with an electrode, is a surface rather than a side surface through dielectrophoresis, drivable mounting efficiency increases, and at the same time, one specific surface is in selective contact with a mounting electrode, and thus a range of selection for driving power may be expanded to include a direct current (DC) power. Therefore, an LED electrode assembly having higher brightness is achieved advantageously.
