Abstract:
A novel anthracene derivative with a large energy gap is provided. An anthracene derivative represented by General Formula (G1) below is provided. In the formula, Ar1 and Ar2 independently represent an aryl group with 6 to 13 carbon atoms in a ring, R1 and R2 independently represent any of hydrogen, an alkyl group with 1 to 4 carbon atoms, or an aryl group with 6 to 13 carbon atoms in a ring, and each of Ar1, Ar2, R1, and R2 may have a substituent and the two substituents may be bonded to each other to form a ring.
