PROBLEM TO BE SOLVED: To enhance an efficiency of an element, lower an operating voltage, and increase design flexibility, by a method wherein at least an inorganic substance layer and an organic substance layer of a hole transportation are laminated on a substrate, and the inorganic substance layer is formed as an oxide film having an wurtzite-containing crystal structure. SOLUTION: A luminous element is constituted by laminating a Si substrate 1, a hole injection electrode 2, an inorganic substance layer 4, an organic substance layer 5, and an electron injection electrode 3, and a drive power source E is connected to each electrode. A buffer layer is provided on a substrate, and an wurtzite compound thin film is formed thereon. A thin film such as an R-Zr-based oxide, etc., is formed on the buffer layer, and on the buffer layer containing at least a species of thin films, the thin film having high crystallinity and superior surface flatness can be formed on a Si substrate. For this reason, a thin film having an wurtzite crystal structure such as a ZnO-based thin film, an AlGaInN-based thin film, or the like is formed as an epitaxial film on the Si substrate via the buffer layer, thereby attaining monocrystal of high quality. |
