There is provided an organic electroluminescence device including: first and second electrode layers; a light-emitting layer 50 disposed between the first electrode layer and the second electrode layer; and a metal-based particle assembly layer being a layer consisting of a particle assembly including 30 or more metal-based particles separated from each other and disposed in two dimensions, the metal-based particles having an average particle diameter in a range of from 200 to 1600 nm, an average height in a range of from 55 to 500 nm, and an aspect ratio in a range of from 1 to 8, the metal-based particles being disposed such that an average distance between adjacent metal-based particles may be in a range of from 1 to 150 nm. The organic electroluminescence device provides enhanced emission and improvement of light extraction efficiency via the metal-based particle assembly layer and thus presents high luminous efficiency. |
