A novel anthracene derivative, a light emitting element containing the derivative, an electronic device containing the derivative, and a light emitting device containing the derivative are provided to improve the luminous efficiency and lifetime of a light emitting element. An anthracene derivative is represented by the formula 1, wherein B1 and B2 are a halogen atom, a cyano group, an acryl group, a carboxyl group, an acyloxy group, an alkoxy group, a pyridyl group, a quinolyl group, an isoquinolyl group or an oxazolyl group, respectively; A is a group represented by -N(Ar11)-alpha-NAr12(Ar13) or a group represented by the formula 1b or 1c; Ar11 to Ar13 are a C6-C25 aryl group, respectively; alpha is a C6-C25 arylene group; Ar21 is a C6-C25 aryl group; R31 is H, a C1-C4 alkyl group or a C6-C25 aryl group; R32 is a C1-C4 alkyl group or a C6-C25 aryl group; Ar31 is a C6-C25 aryl group; beta is a C6-C25 arylene group; and R41 and R42 are H, a C1-C4 alkyl group or a C6-C25 aryl group, respectively.
