摘要：
Objects of the present invention are to provide the following: a novel heterocyclic compound which can be used as a material in which a light-emitting substance of a light-emitting layer in a light-emitting element is dispersed; a novel heterocyclic compound having a high electron-transport property; a light-emitting element having high current efficiency; and a light-emitting device, an electronic device and a lighting device each having reduced power consumption. Provided are a heterocyclic compound represented by General Formula (G1-1) or (G1-2) below, and a light-emitting element, a light-emitting device, an electronic device and a lighting device each including the heterocyclic compound. Such use of the heterocyclic compound represented by General Formula (G1-1) or (G1-2) makes it possible to provide a light-emitting element having high current efficiency, and a light-emitting device, an electronic device and a lighting device each having reduced power consumption.
