Abstract
A light emitting device 1 has a light emitting layer portion in which a p-type cladding layer 2, an active layer 33 and an n-type cladding layer 34 are stacked in this order, and the p-type cladding layer 2 is composed of a p-type MgxZn1-xO (where, 0<x≦1) layer. By forming these layers by the MOVPE process, oxygen deficiency during the film formation is effectively prevented from occurring, and a p-type MgxZn1-xO layer having desirable characteristics can be obtained.
