PROBLEM TO BE SOLVED: To relatively easily constitute a large-area display and set it to the thin-type, long-life, and full-color display at low cost by setting an inorganic hole implantation transport layer to an inorganic insulating hole implantation transport layer with silicon and/or germanium oxide set to major components. SOLUTION: Preferably, when the mean composition of major components is expressed by (Si1-xGex)Oy, then O<=x<=1 and 1.7<=y<=1.99, an inorganic insulating electron implantation transport layer includes silicon oxide (SiO2) and/or germanium oxide (GeO2) as stabilizer, and this light emitting diode includes the constituents, or the major components 80-99 mol% and the stabilizer 1-20 mol% relative to the whole components. This light emitting diode is so constituted that a substrate 1, a positive electrode 2, an inorganic hole implantation layer 3, a light emitting layer 4, a high-resistance inorganic insulating electron implantation transport layer 5, and a negative electrode (electron implantation electrode) 6 are sequentially laminated.
