Abstract
An LED array includes a substrate and a semiconductor structure layer provided on the substrate. The semiconductor structure layer includes a first semiconductor layer, an active layer formed on the first semiconductor layer, and a second semiconductor layer formed on the active layer. The semiconductor structure layer is partitioned into a plurality of light emitting sections by grooves formed in the semiconductor structure layer. Each groove is defined by two opposite side faces of adjacent light emitting sections. Each side face has a recessed and protruding configuration. In one embodiment, the protrusions and recesses of one side face of one light emitting section fit in respective recesses and protrusions of a corresponding side face of an adjacent light emitting section.
