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
1
is B, and X
1
and X
2
each independently represent O or N—R wherein at least one of X
1
and X
2
is N—R.

On-Top π-Stacking of Quasiplanar Molecules in Hole-Transporting Materials: Inducing Anisotropic Carrier Mobility in Amorphous Films
were designed and synthesized as hole‐transporting materials. X‐ray structural analyses revealed that these compounds form on‐top π‐stacking aggregates in the crystalline state. TRMC measurements showed that high levels of anisotropic charge transport were induced in the direction of the π‐stacking. Surprisingly, even in vacuum‐deposited amorphousfilms, these compounds retained some of the face‐on π‐stacking
