LIGHT-EMITTING ELEMENT AND PRODUCTION METHOD THEREFOR
ZnO is used in the present invention to inexpensively obtain a light-emitting element having a large area. A ZnO transparent conductive film (conductive layer) (12) is formed on a transparent substrate (11), after which an n-type ZnO thin film (n-type layer) (13) is formed on the ZnO transparent conductive film (12). A microparticle layer (14) that is a p-type layer is formed on the n-type ZnO thin film (13). By running electrical current between an n-side electrode (15) and a p-side electrode (16) as illustrated in the figures for this application, the light-emitting element (10) emits lights mainly from the microparticle layer (14). The microparticle layer (14) is formed by sintering a plurality of types of microparticles. The plurality of types of microparticles corresponds to microparticles that employ different materials as the main component thereof or microparticles for which the production conditions differ. At least one of the types of microparticles is a ZnO microparticle.
