A compound is represented by a formula (1). n is 2 to 4, m is 1 to 4, q is 0 to 3, and m+n+q=6; CN is a cyano group; Dis a group represented by a formula (2), (3) or (3X), the plurality of Dare the same; and Rx is a hydrogen atom or substituent. Rto Rare each independently a hydrogen atom or substituent. Rto Rand Rto Rare each independently a hydrogen atom or substituent; p, px and py are each independently 1 to 4; A to C are each independently a cyclic structure represented by a formula (131) or (132). Rand Rare each independently a hydrogen atom or substituent. Xis a sulfur atom or the like, and * represents a bonding position with a carbon atom of a benzene ring in the formula (1).
