Novel styryl compounds represented by the following general formulae (1)
and (2): ##STR00001## wherein R.sup.1 to R.sup.10 each independently
represent hydrogen atom, an alkyl group, an alkoxyl group, an aryl group,
an aryloxyl group, a condensed polycyclic group, a heterocyclic group,
amino group, an alkylamino group, an arylamino group, cyano group, nitro
group, hydroxyl group or a halogen atom, adjacent groups among groups
represented by R.sup.1 to R.sup.10 may be bonded to each other and form a
saturated or unsaturated carbon ring, and A, B, C, D, A', B', C' and D'
each independently represent a substituted or unsubstituted alkyl group
or aryl group having a specific structure; and an organic
electroluminescence device comprising a film of organic compounds
comprising at least a light emitting layer, wherein at least one of the
layers of the film of organic compounds comprises the novel styryl
compound. The organic electroluminescence device has excellent heat
resistance, a high efficiently of light emission and a long life and
emits blue light of a high purity. The novel styryl compounds provide the
advantageous properties to the organic electroluminescence device.
