摘要：
A substance that facilitates hole injection and has high triplet excitation energy is provided. A light-emitting element having high emission efficiency is provided. A light-emitting element driven with a low voltage is provided. Or a light-emitting element having a long lifetime is provided. Provided is a light-emitting element including a triazolo[4,3-f]phenanthridine derivative or a triazolo[3,4-a]isoquinoline derivative. Provided is a triazolo[4,3-f]phenanthridine and triazolo[3,4-a]isoquinoline derivatives, which are novel and can be used for the light-emitting element.
