Abstract
An object is to provide a novel substance which exhibits blue light emission with excellent color purity, and to provide a light emitting element and a light emitting device using the novel substance. A stilbene derivative represented by the general formula (G1) is provided. Note that in the general formula (G1), each of A1 and B1 represents any one of structures represented by the following general formulae (G1-1) to (G1-4). In addition, in each of the general formulae (G1-1) to (G1-4), each of R1 to R24 represents any one of hydrogen and an alkyl group having 1 to 4 carbon atoms. Such a stilbene derivative can exhibit blue light emission with excellent color purity.
