Light emitting element, light emitting device, and electronic device
摘要:
An object of the present invention is to provide a light emitting element which has low driving voltage and can increase lifetime longer than a conventional light emitting element. One feature is to include a plurality of layers which includes a layer containing a light emitting substance between first and second electrodes, in which at least one layer of the plurality of layers contains a carbazole derivative represented by General Formula (1) and a substance having an electron accepting property with respect to the carbazole derivative represented by General Formula (1). By employing this structure, the above object can be achieved.
