Light-Emitting Element, Light-Emitting Device and Electronic Device |
| abstract |
A light-emitting element with improved emission efficiency is provided. The light-emitting element includes a light-emitting layer in which a first light-emitting layer and a second light-emitting layer are stacked in contact with each other over an anode, and a first substance serving as an emission center substance in the second light-emitting layer is the same as a main substance in the first light-emitting layer. Note that a second substance is added to the first light-emitting layer for stabilization of film quality, and a third substance serving as a host material to disperse the first substance serving as an emission center substance is included in the second light-emitting layer. In the light-emitting element, the second substance and the third substance are substances having energy gaps (or triplet energy) larger than the first substance. |
