Patent abstract
An organic electroluminescent device (1) including: an emitting layer (14) between a pair of electrodes that are an anode (12) and a cathode (17), and a suppressing layer arranged between an electrode and the emitting layer (14), the suppressing layer regulating the amount of electrons or holes supplied to the emitting layer (14). For example, the electroluminescent device wherein the electron-injection-suppressing layer (15) or a hole-injection-suppressing layer is formed as the suppressing layer. The organic electroluminescent device is improved in emission efficiency.
