A method for fabricating a light emitting device, comprising: forming a plurality of light emitting stacked layers above a substrate; forming and patterning a current blocking (CB) layer on the light emitting stacked layers; forming a transparent conductive layer covering the light emitting stacked layers and the current blocking layer; etching the transparent conductive layer and exposing a reserved region for a first pad electrode and a mesa structure, respectively; and etching an exposed portion of the light emitting stacked layers and a portion of the current blocking layer to form a remaining current blocking layer, the mesa structure and a first opening.
