Abstract:
Provided is a light-emitting diode chip including a semiconductor device layer, a first electrode, a current-blocking layer, a current-spreading layer, and a second electrode. The semiconductor device layer includes a first-type doped semiconductor layer, a second-type doped semiconductor layer, and a light-emitting layer therebetween. The first electrode is electrically connected to the first-type doped semiconductor layer. The current-blocking layer is on the second-type doped semiconductor layer. The current-blocking layer is between the current-spreading layer and the second-type doped semiconductor layer. The second electrode is on the current-spreading layer and electrically connected to the second-type doped semiconductor layer. The current-blocking layer has a first surface facing the semiconductor device layer, a second surface back on to the semiconductor device layer, and a first inclined surface. The first inclined surface is connected between the first surface and the second surface and tilted with respect to the first surface and the second surface.
