Abstract
An organic electroluminescent device includes a hole-injecting electrode, an electron-injecting electrode and a blue light-emitting layer which is provided between the electrodes and contains a host material, a luminescent dopant and an assist dopant for complementing carrier transport of the host material. When the host material is an electron-transporting material, the assist dopant has a smaller absolute HOMO (Highest Occupied Molecular Orbital) energy level than the host material and a higher hole mobility than the host material.
