The present invention is a multi-wavelength luminous organic electroluminescent element, which has a cathode, an anode, and at least one organic layer between the cathode and the anode that contains a variety of luminescent materials. The luminescent material emits light, and it is designed such that the shortest wavelength of luminescence from the luminescent material includes delayed fluorescence. Accordingly, it is possible to provide a multi-wavelength emission-type organic electroluminescence device capable of improving short-wavelength emission efficiency to improve color tone, having a large degree of freedom in design, and realizing a simple structure. |
