Light emitting device |
| abstract |
An object of this invention is to provide a light emitting element of long life. In particular, it is a problem to provide a white light emitting device having a long life. Moreover, it is a subject to provide the light emitting element with high luminous efficiency. In particular, it is a problem to provide a white light emitting device having high luminous efficiency.n n n In a light emitting device having a first light emitting layer including a first light emitting material and a second light emitting layer formed between the anode and the cathode and in contact with the first light emitting layer, and further comprising a second light emitting material, the first light emitting layer is provided. The layer is divided into a layer located on the anode side and a layer located on the cathode side. At this time, a hole transportable host material is used for the layer located on the anode side, and an electron transportable host material is used for the layer located on the cathode side. |
