Abstract
A light emitting diode array in which, when viewed from the above, the shape of an almost square light emitting diode is square-chamfered or round-chamfered at the corners thereof in order to minimize light leakage at a reverse mesa surface to allow an electrode layer to surround the three directions of a light emitting unit, and part in the vicinity of the corner of the reverse mesa surface is extended up to a substrate unit to cover it. Accordingly, the light emitting diode array minimized in light leakage at the reverse mesa surface can be provided.
