Abstract:
1. A light emitting device comprising: an LED chip and a mounting substrate, said LED chip comprising an n-type nitride semiconductor layer, a nitride light emission layer, a p-type nitride semiconductor layer, an anode electrode, and a cathode electrode, said n-type nitride semiconductor layer having a first surface, said nitride light emission layer being disposed on said first surface of said n-type nitride semiconductor layer, said p-type nitride semiconductor layer being disposed on said nitride light emission layer, said anode electrode being opposite of said nitride light emission layer from said p-type nitride semiconductor layer and covering said p-type nitride semiconductor layer, said cathode electrode being disposed on said first surface of said n-type nitride semiconductor layer, said mounting substrate being configured to mount said LED chip, said mounting substrate having a first patterned conductor which is coupled to said cathode electrode through a cathode bump and a second patterned conductor which is electrically and physically connected to anode bumps, said anode bumps being electrically and physically connected to said anode electrode, said LED chip comprising dielectric layers which have an arrangement which resembles an island and a light reflective conductive film covering said dielectric layers, said dielectric layers having a refractive index which is smaller than a refractive index of said p-type nitride semiconductor layer, said dielectric layers being located between said p-type nitride semiconductor layer and said anode electrode, said p-type nitride semiconductor layer having first regions which are overlapped with said anode bumps in a planer view, respectively, said dielectric layers being not overlapped with said first regions, said light reflective conductive film being located between said anode electrode and said dielectric layers, and said anode electrode does not penetrate said light reflective conductive film.
