Abstract
A light emitting device 100 has a structure in which a p type InGaAs layer 7 as an electrode contact layer and an ITO electrode layer 8 as an oxide transparent electrode layer are formed in the order in a first major surface 17 side of a light emitting layer section 24. In a second major surface 18 side of the light emitting layer section 24, an n type InGaAs layer 9 as an electrode contact layer and an ITO electrode layer 10 as an oxide transparent electrode layer are formed in the order. The ITO electrode layers 8 and 10 together with the p type InGaAs layer 7 and the n type InGaAs layer 9 are formed on the respective both major surfaces 17 and 18 of the light emitting layer section 24 so as to cover the respective both major surfaces 17 and 18 in the entirety thereof.
