An electroluminescence device contains a carrier transporting layer comprising
a liquid crystal compound represented by
wherein A and B denote a naphthalene-2,6-diyl skeleton optionally substituted
with one or two of F, Cl, Br, CH3 and CF3, at least one of
A and B comprising a naphthalene-2,6-diyl skeleton having one to four CH groups
replaced with N; X and X denote O, S, OOC
or COO; and one of R and R denotes H, F, Cl, Br, CF3
or a linear or branched alkyl group having 1-20 carbon atoms, and the other
one of R and R denotes a linear or branched alkyl group having 3-20 carbon
atoms, said alkyl groups being independently capable of including one methylene
group which can be replaced with O, S, CHCH
or CC so long as heteroatoms are not adjacent to each other.
