It is an object of the present invention to provides the light emitting diode having a light emitting part of an AlGaInP type, and having a current diffusion layer which includes In on a light emitting side of the light emitting part, so that the generation of hillocks is effectively inhibited and the brightness of the light emitting diode is increased. Locations of mobile stations may be determined using one or more MS locating technologies based on, e. A periphery of the package body is laterally recessed, such that a connection surface of the grounding element is electrically exposed and electrically connected to the EMI shield.
