The present invention relates to a light emitting layer material comprising: a polycyclic aromatic compound (1) in which a plurality of aromatic rings are linked by a boron atom and a oxygen atom or a nitrogen atom; and a specific anthracene-based compound (3) that achieves optimum light-emission characteristics in combination with said polycyclic aromatic compound. With this light emitting layer material having optimum light emitting characteristics, it is possible to provide an excellent organic EL element.Ring A to ring C are an aryl ring or the like, Y<sup>1</sup>is B (boron), X<sup>1</sup>and X<sup>2</sup>are -O- or >N-R (provided that at least one is -O-), X is a group represented by formula (3-X1), (3-X2), or (3-X3), Y is -O-, -S- or >N-R<sup>29</sup>, R<sup>29</sup>is a hydrogen atom or an optionally substituted aryl, Ar<sup>1</sup>to Ar<sup>4</sup>are phenyl, a group represented by formula (4), or the like, and both Ar<sup>1</sup>and Ar<sup>3</sup>do not simultaneously represent a phenyl. |
