Electroluminescence element

An electroluminescence element comprising an emissive element layer including an organic compound between a hole injecting electrode and an electron injecting electrode, wherein

• the emissive element layer includes a plurality of emissive layers, and at least a hole transport layer is provided between the hole injecting electrode and a first emissive layer, of the plurality of emissive layers, which is disposed closest to the hole injecting electrode, and at least an electron transport layer is provided between the electron injecting electrode and a second emissive layer, of the plurality of emissive layers, which is disposed closest to the electron injecting electrode, and
• when an amount of time required for holes injected from the hole injecting electrode to pass through the hole transport layer and the first emissive layer to reach the second emissive layer is represented by Th and an amount of time required for electrons injected from the electron injecting electrode to pass through the electron transport layer and the second emissive layer to reach the first emissive layer is represented by Te, the ratio of Th/Te satisfies a relationship 0.5<(Th/Te)<2.5.
