Claim of US Patent No. 10,368,417

1. A display device comprising a semiconductor light-emitting device, wherein the semiconductor light-emitting device comprises:a first conductive semiconductor layer;
a second conductive semiconductor layer provided with a lateral surface to overlap with the first conductive semiconductor layer;
a first conductive electrode electrically connected to the first conductive semiconductor layer; and
a second conductive electrode electrically connected to the second conductive semiconductor layer,
wherein the second conductive semiconductor layer is provided with an inclined portion inclined with respect to the lateral surface, and the second conductive electrode is configured to cover the inclined portion,
wherein an upper surface the semiconductor light-emitting device includes one side having both ends forming an obtuse angle with respect to other sides of the upper surface, and
wherein the inclined portion is formed at the one side.
