Abstract:
1. A LED chip, comprising: a substrate, wherein an orthographic projection of the substrate comprises five or more edges; a semiconductor element, comprising a first-type semiconductor layer, a light-emitting layer, and a second-type semiconductor layer stacked in order from the substrate, wherein a recess is formed on the second-type semiconductor layer, and a portion of the first-type semiconductor layer is exposed to the environment by the recess; a conductive layer, disposed on the second-type semiconductor layer; a first electrode, disposed on the portion of the first-type semiconductor layer that is exposed by the recess; a second electrode, disposed on the conductive layer; and a first circular electrode, disposed on the conductive layer, wherein the first circular electrode extends along the edges of the substrate and is electrically connected to the second electrode so as to form a closed loop circuit.
