Japanese Patent JP6771065
Kind Code:
B2
Abstract:
To provide a light emitting device capable of improving light extraction efficiency.SOLUTION: A light emitting device 1 includes: a semiconductor laminate structure portion 6 having an n-type semiconductor layer 3, a light emitting layer 4, and a p-type semiconductor layer 5 which are laminated in order on a surface 2A of a substrate 2; a plurality of concave portions 16 which are formed in a predetermined current injection region on a surface of a p-type semiconductor layer side in the semiconductor laminate structure portion 6 so as to enter the inside of the semiconductor laminate structure portion and which extend from the p-type semiconductor layer 5 up to the inside of the semiconductor laminate structure portion; a first insulating film 12 formed in a part of the current injection region on a surface of a p-type semiconductor layer side; a p-side transparent electrode layer which is formed on a surface of the p-type semiconductor layer 5 and which covers the whole area or a substantially whole area of the predetermined current injection region on the surface of a p-type semiconductor layer side and simultaneously covers the first insulting film 12; and a p-side electrode 15 which is formed at a position facing a surface of the first insulating layer 12 on a surface on a side opposite to the p-type semiconductor layer 5 in the p-side transparent electrode layer 14.SELECTED DRAWING: Figure 2
