WHITE ORGANIC LIGHT EMITTING DEVICE |
| 摘要 |
Disclosed is a white organic light emitting device for enhancing emission efficiency and a color viewing angle or a color reproduction rate. The white organic light emitting device includes a first emission part between a first electrode and a second electrode, the first emission part having a first emission layer, a second emission part on the first emission part, the second emission part having a second emission layer, and a third emission part on the second emission part, the third emission part having a third emission layer. At least two emission layers of the first to third emission layers emit lights having a same color to enhance emission efficiency and a color viewing angle, and the at least two emission layers are adjacent to each other. |
