Abstract: It is an object of the present invention to provide an organic EL element including a capping layer constituted by two layers consisting of a first capping layer and a second capping layer that has a refractive index that is higher than that of the first capping layer, in order to improve the light extraction efficiency compared with an organic EL element including a capping layer constituted by a single layer. The present invention provides an organic electroluminescent element at least including an anode, a hole transport layer, a light emitting layer, an electron transport layer, a cathode, and a capping layer arranged in this order, wherein the capping layer has a structure constituted by two layers consisting of a first capping layer and a second capping layer, a refractive index of the second capping layer is higher than a refractive index of the first capping layer throughout a wavelength range from 450 to 650 nm, and the second capping layer contains an arylamine compound having a specific structure.
