Claim Text:
1. A light emitting device comprising: a first semiconductor multilayer film mirror of a first conductivity type; a second semiconductor multilayer film mirror of a second conductivity type, the second conductivity type being different than the first conductivity type; an active layer between the first semiconductor multilayer film mirror and the second semiconductor multilayer film mirror; a third semiconductor multilayer film mirror of a semi-insulating type between the first semiconductor multilayer film mirror and the active layer; a contact layer of the first conductivity type between the third semiconductor multilayer film mirror and the active layer; a first electrode electrically connected to the first semiconductor multilayer film mirror; a second electrode electrically connected to the second semiconductor multilayer film mirror; and a third electrode having ohmic contact with the contact layer, wherein the third semiconductor multilayer film mirror is formed of a material having a bandgap energy higher than an energy of light generated in the active layer.
