<P>PROBLEM TO BE SOLVED: To provide a light-emitting element having high luminous efficiency, and to provide a light-emitting device and electronic equipment which consumes low power and is driven at low voltage by providing a new carbazole derivative. <P>SOLUTION: There is disclosed a carbazole derivative represented by general formula (1). In the formula, α<SP POS="POST">1</SP>, α<SP POS="POST">2</SP>, α<SP POS="POST">3</SP>, and α<SP POS="POST">4</SP>each represent an arylene group having less than or equal to 13 carbon atoms forming a ring; Ar<SP POS="POST">1</SP>and Ar<SP POS="POST">2</SP>each represent an aryl group having less than or equal to 13 carbon atoms forming a ring; R<SP POS="POST">1</SP>represents any of a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, and a substituted or unsubstituted biphenyl group; and R<SP POS="POST">2</SP>represents any of an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, and a substituted or unsubstituted biphenyl group. In addition, l, m, and n are each independently 0 or 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
