ORGANIC LIGHT EMITTING ELEMENT |
| 摘要 |
An organic light emitting element is disclosed which includes: an anode and a cathode formed on a substrate and disposed to face each other; and a stack formed between the anode and the cathode and configured to include a hole transport layer, a first light emission layer, a second emission layer and an electron transport layer. The first light emission layer adjacent to the anode includes a host with band gaps of 1.00 eV˜2.70 eV and 2.76 eV˜4.00 eV. Such an organic light emitting element allows at least two light emission layers to be included into a single stack so that a driving voltage is reduced. |

1. An organic light emitting element comprising:
an anode and a cathode formed on a substrate and disposed to face each other; and a stack formed between the anode and the cathode and configured to include a hole transport layer, a first light emission layer, a second light emission layer and an electron transport layer, wherein the first light emission layer adjacent to the anode includes a host with band gaps of 1.00 eV˜2.70 eV and 2.76 eV˜4.00 eV. |
