| 摘要 |
An organic electroluminescent device includes an anode electrode layer (2), a cathode electrode layer (3) opposed to the anode electrode layer (2), and a luminous layer (30) containing an organic compound disposed between the anode electrode layer (2) and the cathode electrode layer (3). An excitation state of the organic compound in the luminous layer (30) is created upon a hole injection from the anode electrode layer (2), and an electron injection from the cathode electrode layer (3), thereby causing light emission in the organic electroluminescent device. An electron-accepting material (20) is provided in at least one hole transportation layer (11, 12) capable of transporting holes injected from the anode electrode layer (2) disposed between the anode electrode layer (2) and the cathode electrode layer (3), and the electron-accepting material (20) is positioned at a side which is not adjacent to the anode electrode layer (2). <IMAGE> |
