Disclosed is a novel benzoxazole derivative which has high excitation energy, particularly high triplet excitation energy, and is a bipolar substance. A benzoxazole derivative represented by the following General Formula (G1) is provided.
In the formula, R
1
and R
2
independently represent a hydrogen atom, an alkyl group with 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group with 6 to 13 carbon atoms, substituents of the substituted aryl group may be bonded to form a ring which may form a spiro ring structure, R
11
to R
14
independently represent a hydrogen atom, a halogen, an alkyl group with 1 to 4 carbon atoms, or an unsubstituted aryl group with 6 to 10 carbon atoms, a bond formed between any two of α, β, and γ forms a carbazole skeleton, and n is 0 to 3.
