<p>Concaves and convexes are formed in a light transmitting conductive layer provided on a surface of a light emitting device made of nitride semiconductor, thereby light emitted from a light emitting layer is totally reflected repeatedly in a semiconductor lamination portion and a substrate and can be effectively taken out without attenuation, and external quantum efficiency can be improved. A semiconductor lamination portion (6) is formed by laminating nitride semiconductor layers including an n-type layer (3) and a p-type layer (5) on one side of a substrate (1) so as to form a light emitting layer, and a light transmitting conductive layer (7) is provided at a surface side of the semiconductor lamination portion. A concave-convex pattern, i.e., concaves (7a), is provided on a surface of the light transmitting conductive layer. A p-side electrode (8) is provided on the light transmitting conductive layer, and an n-side electrode (9) is electrically connected to the n-type layer exposed by etching a part of the semiconductor lamination portion.</p> |
