Abstract
A novel organic compound with which the emission characteristics, emission efficiency, and reliability of a light-emitting element can be improved is provided. The organic compound has an imidazo[1,2-f]phenanthridine skeleton and a dibenzothiophene skeleton or a dibenzofuran skeleton bonded through an arylene group. The light-emitting element including the organic compound in a light-emitting layer shows high efficiency and low power consumption.
