Provided is an organic electroluminescence device including a first electrode, a hole transport region disposed on the first electrode, an emission layer disposed on the hole transport region, an electron transport region disposed on the emission layer, and a second electrode disposed on the electron transport region. The hole transport region includes a first hole transport layer disposed adjacent to the first electrode, the first hole transport layer including a first organic compound having a first dielectric constant and a second hole transport layer disposed between the first hole transport layer and the emission layer, the second hole transport layer including a second organic having a second dielectric constant which is greater than the first dielectric constant.
