A first electrode and an isolation layer are formed on one side of an N-type semiconductor layer of the light emitting diode, the isolation layer comprises a first part and a second part, the first part covers a light emitting area, and the second part is located below a main extension part of the first electrode. Or the second part is positioned below the main extension part and the body part. Through the arrangement of the isolation layer, the contact area of the first electrode made of the metal material and the semiconductor epitaxial laminated layer is reduced, so that the interface roughness caused by contact diffusion of the metal and the epitaxial laminated layer is reduced, and the light emitting efficiency can be improved. Meanwhile, the contact surface of the current expansion layer and the epitaxial lamination layer is flat and smooth, the mirror surface effect is good, light reflection can be improved, and the light emitting efficiency is improved. And on the other hand, the secondary extension part of the first electrode and the epitaxial lamination layer form ohmic contact, so that good ohmic contact is formed, and normal voltage of the light-emitting diode is ensured.
