Abstract
An organic electroluminescence device including a pair of electrodes and at least one organic compound layer comprising a light-emitting layer between the pair of electrodes, wherein a refractive index of at least one of the light-emitting layer or an organic compound layer on the light extraction side of the light-emitting layer is 1.6 or less. An organic EL device in which luminescence can extracted with high efficiency and luminescence of high brightness can be obtained.
