An organic EL device comprising organic compound layers, at least one of
which has a skeleton represented by formula (I): ##STR00001## where
L.sub.0 is any one of o-, p-, and m-phenylene groups which have two,
three or four rings and which may have a substituent with the proviso
that when L.sub.0 is a phenylene group having four rings, the phenylene
group may have an unsubstituted or substituted aminophenyl group
somewhere therein, R.sub.01, R.sub.02, R.sub.03 and R.sub.04 are each any
one of the following groups: ##STR00002## where R.sub.11, R.sub.12,
R.sub.13, R.sub.14, R.sub.15, R.sub.16 and R.sub.17 are each a
substituted or unsubstituted aryl group, and r.sub.1, r.sub.2, r.sub.3
and r.sub.4 are each an integer of 0 to 5 with the proviso that
r.sub.1+r.sub.2+r.sub.3+r.sub.4 1, is less susceptible to physical
changes, photochemical changes and electrochemical changes, and can emit
light having various colors with high reliability and high light emission
efficiency.
