PROBLEM TO BE SOLVED: To provide an organic electroluminescent element material having a high emission efficiency, a low drive voltage, a long emission life, a production aptitude by wet process, and pixel defect inhibitory.SOLUTION: An organic electroluminescent element material is a compound represented by following general formula (1). (In the general formula (1), R-Rrepresent a substituent group, respectively and independently. When there are a plurality of R-R, respectively, the R-Rmay be the same or different, and may be bonded to form a ring. n1 represents an integer of 1-8, n2 represents an integer of 0-3, and n3 represents an integer of 0-4. Cbz represents a carbazolyl group that may be substituted. Lrepresents a single bond or bivalent coupling group. X represents an oxygen atom or sulfur atom). |
