The objective of the invention is to provide a polycyclic aromatic compound in which solubility to a solvent, film formability, wet coatability, thermal stability, and in-plane orientation are improved. This objective is achieved by a light emission layer-forming composition comprising: as a first component, at least one type of dopant material selected from the group consisting of polycyclic aromatic compounds represented by general formula (A) and polycyclic aromatic oligomer compounds including a plurality of structures represented by general formula (A); as a second component, a specific low-molecular-weight host material; and, as a third component, at least one type of organic solvent. In formula (A), ring A, ring B, and ring C each independently represent an aryl ring or a hetero aryl ring, Y

is N—R.
An organic electroluminescent element includes a light emitting layer including, as host materials, an anthracene-based compound represented by the following general formula (1) and a dibenzochrysene-based compound represented by the following general formula (2), and further including a dopant material.
(X and Ar
