英文摘要	There is provided a light emitting device and a process for producing the same in that the light emission efficiency is high, the range of selection of the material is broad, and a device array of a large area can be formed. On a substrate 11 comprising quartz glass, an n-type clad layer 12 comprising a non-single crystal body of n-type AlGaN, a light emitting layer 13 containing plural microcrystals 13a comprising ZnO, and a p-type clad layer 14 comprising a non-single crystal body of p-type BN are laminated in this order. Between the n-type clad layer 12 and the p-type clad layer 14, an insulating layer 15 is formed to fill the gap among the microcrystals 13a to prevent a leaking electric current. The insulating layer 15 is formed by oxidizing the surface of the n-type clad layer 12. Because the light emitting layer 13 contains the plural microcrystals 13a having an increased crystallinity, the light emission efficiency is increased, the range of selection of the materials of the light emitting layer 13, the n-type clad layer 12, the p-type clad layer 14 and the substrate 11 is broadened, and a device array of a large area can be formed.
