Organic electroluminescent device for panel includes at least two thin films of an organic compound selected from a luminous layer, an electron injecting layer, and an electron transporting layer provided between electrodes

摘要

At least two thin films of an organic compound selected from a luminous layer, an electron injecting layer, and an electron transporting layer are provided between electrodes having different polarity. At least two thin films of an organic compound selected from a luminous layer, an electron injecting layer, and an electron transporting layer are provided between electrodes having different polarity. The luminous layer generates blue light. The ionization potential of the electron injecting layer or that of the electron transporting layer is higher than that of the luminous layer.
