Semiconductor light emitting device
First Claim
1. A semiconductor light emitting device comprising:
- a semiconductor light emitting portion having a first contact layer of a first conductivity, a second contact layer of a second conductivity and an active layer sandwiched between the first and second contact layers;
a transparent electrode which substantially entirely covers a surface of the second contact layer in ohmic contact with the surface of the second contact layer and is transparent to a wavelength of light emitted from the semiconductor light emitting portion; and
a metal reflection film which is opposed to substantially the entire surface of the transparent electrode and electrically connected to the transparent electrode, and reflects the light emitted from the semiconductor light emitting portion and passing through the transparent electrode toward the semiconductor light emitting portion.

Abstract
A semiconductor light emitting device includes a semiconductor light emitting portion having a first contact layer of a first conductivity, a second contact layer of a second conductivity and an active layer sandwiched between the first and second contact layers. The device further includes a transparent electrode which substantially entirely covers a surface of the second contact layer in ohmic contact with the surface of the second contact layer and is transparent to a wavelength of light emitted from the semiconductor light emitting portion, and a metal reflection film which is opposed to substantially the entire surface of the transparent electrode and electrically connected to the transparent electrode, and reflects the light emitted from the semiconductor light emitting portion and passing through the transparent electrode toward the semiconductor light emitting portion.
