Patent ID: 8110980

Claim:
A light-emitting device comprising a light-emitting element which comprises an anthracene derivative between a pair of electrodes, wherein the anthracene derivative is represented by the General Formula (1), wherein each of B 1 and B 2 represents one selected from the group consisting of halogen, a cyano group, an acyl group, a carboxyl group, an acyloxy group, an alkoxy group, a pyridyl group, a quinolyl group, an isoquinolyl group, and an oxazolyl group, and wherein A represents a substituent given by one of General Formulae (1-1) to (1-3): wherein: each of Ar ll to Ar 13 represents an aryl group having 6 to 25 carbon atoms; α represents an arylene group having 6 to 25 carbon atoms; Ar 21 represents an aryl group having 6 to 25 carbon atoms; R 31 represents one selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 25 carbon atoms; R 32 represents an alkyl group having 1 to 4 carbon atoms or an aryl group having 6 to 25 carbon atoms; Ar 31 represents an aryl group having 6 to 25 carbon atoms; β represents an arylene group having 6 to 25 carbon atoms; and each of R 41 and R 42 represents one selected from the group consisting of a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 25 carbon atoms.
