Abstract

Provided is a light-emitting device that can have sufficient device characteristics even with a smaller number of stacked layers in an EL layer and a thicker light-emitting layer than a conventional one by using, as an organic compound used for the EL layer of the light-emitting device, a material that can increase not only a property of carrier transport to the light-emitting layer but also a property of carrier injection from an electrode.
