A light emitting element in use for an LED array comprises an electrode layer, a semiconductor light emitting layer consisting of a p-type semiconductor layer, an active layer and an n-type semiconductor layer, a first wiring layer formed along and in parallel to one side of the semiconductor light emitting layer, and a plurality of second wiring layers extending from the first wiring layer to the semiconductor light emitting layer and electrically connected to the n-type semiconductor layer on a surface of the semiconductor light emitting layer, wherein a plane shape of the semiconductor light emitting layer comprises two short sides including a portion inclined from a line perpendicular to a upper and a lower sides, and a vertical line from a vertex where the upper side and the short side meet crosses the lower side of the adjacent light emitting element.
