| 摘要 |
The objective of the present invention is to provide an organic EL display device capable of driving a lower voltage. The organic EL display device includes a first light emitting part (310) which has a first light emitting layer (313) which is formed between an anode electrode (285) and a cathode electrode (287) and emits light by a potential difference between the anode electrode and the cathode electrode, and a hole injection layer (311) including amorphous carbon touching the anode electrode, a second light emitting part (320) which has a second light emitting layer (322) is formed between the first light emitting part and the cathode electrode and emits light by a potential difference between the anode and the cathode, an n-type charge generation layer (331) which is formed between the first light emitting part and the second light emitting part, touches the first light emitting part, and supplies electrons to the first light emitting part, and a p-type charge generation layer (332) which is formed between the n-type charge generation layer and the second light emitting part and includes amorphous carbon, and supplies holes to the second light emitting part. |
