CARBAZOLE DERIVATIVE, AND LIGHT EMITTING ELEMENT AND LIGHT EMITTING DEVICE USING THE CARBAZOLE DERIVATIVE |
摘要 |
It is an object of the present invention to provide a material which is excellent in a hole injecting property and a hole transporting property, and to provide a light emitting element and a light emitting device using a material which is excellent in a hole injecting property and a hole transporting property. The present invention provides a carbazole derivative represented by a general formula (1). The carbazole derivative according to the present invention is excellent in the hole injecting property. By using the carbazole derivative according to the present invention as a hole injecting material for a hole injecting layer of a light emitting element, a driving voltage can be reduced. In addition, a lower driving voltage, improvement of the luminous efficiency, a longer life time, and higher reliability can be realized by applying the material to a light emitting element or a light emitting device. |
