Abstract
The light emitting device comprises a mounting substrate and an LED chip which comprises an n-type nitride semiconductor layer, a nitride light emission layer on the n-type nitride semiconductor layer, p-type nitride semiconductor layer on the nitride light emission layer, an anode electrode opposite of the nitride light emission layer from the p-type nitride semiconductor layer, and a cathode electrode on the n-type nitride semiconductor layer. The mounting substrate has a patterned conductor which is connected to the cathode electrode through a bump and also connected to the anode electrode through a bump. The LED chip further comprises one or more dielectric layer between the p-type nitride semiconductor layer and the anode electrode to have an arrangement which resembles an island. The p-type nitride semiconductor layer has a first region which is overlapped with the bump. The dielectric layer is not formed within the first region.
