Abstract
A light emitting diode chip includes: a first conductivity type semiconductor layer; a mesa disposed on a partial region of the first conductivity type semiconductor layer, and including an active layer and a second conductivity type semiconductor layer; a transparent electrode being in ohmic contact with the second conductivity type semiconductor layer; a first current spreader being in ohmic contact with the first conductivity type semiconductor layer; a second current spreader electrically connected to the transparent electrode; an insulation layer covering the mesa, the first current spreader and the second current spreader, and including a distributed Bragg reflector. A lateral distance between the first current spreader and the mesa is larger than a thickness of the insulation layer, and a first side surface of the first current spreader close to the mesa is longer than the second side surface thereof.
