PROBLEM TO BE SOLVED: To provide a light emitting element exhibiting excellent emission efficiency and durability (lifetime), and to provide highly reliable light emitting device and electronic apparatus comprising that light emitting element. SOLUTION: The light emitting element 1 is constituted by interposing an electron transport layer 4 principally comprising an inorganic semiconductor material, a light emitting layer L touching the electron transport layer 4, and a hole transport layer 5 touching the light emitting layer L between a negative electrode 3 and a positive electrode 6 wherein the electron transport layer 4 principally comprises a tubular inorganic semiconductor material and further contains a granular inorganic semiconductor material. A light emitting material is bonded (adsorbed) to the inner and outer circumferential surface of the tubular inorganic semiconductor material and to the surface of the granular inorganic semiconductor material.
