Abstract: This benzonitrile derivative has the structure represented by general formula (1). [In the formula, each of substituent groups D1-D5 independently represents a carbazolyl group, and at least one thereof has a structure having a chirality-producing section. However, there is no case in which D1-D5 are all the same. Each of D1-D5 may independently further have a substituent group.]
