Abstract
This invention provides a GaN-based light-emitting diode of which luminous efficiency is improved and a luminous device using the same. In the present invention, a luminous layer (3) composed of GaN-based semiconductor and a p-type GaN-based semiconductor (4) are formed in order on a n-type GaN-based semiconductor layer (2), and in appearance of the p-type GaN-based semiconductor (4), a p-type ohrnic electrode (P2) is formed as a pattern with window, and a reflection layer (P5) of metal for reflecting light from the luminous layer (3) passing through the window is formed to interpose the p-type ohmic electrode (P2) with the p-type GaN-based semiconductor layer (4),and a protection film (P4) composed of insulation material is interposed between the reflection layer (P5) and the p-type ohmic electrode (P2). In a preferable embodiment of the GaN-based light-emitting diode, the most surface layer of the reflection layer (P5) is used as bonding layer, or the bonding layer is furthermore formed over the reflection layer (P5), and the bonding layer and base material for mounting are joined by conductive joining material.
