An organic electroluminescence device includes two or more emitting units disposed between an anode and a cathode, and an intermediate layer, in which the intermediate layer contains a phenanthroline compound, the laminated emitting unit includes a first emitting layer containing a first host material and a second emitting layer containing a second host material, and a triplet energy T.sub.1(H1) of the first host material and a triplet energy T.sub.1(H2) of the second host material satisfy a relationship of a numerical formula (Numerical Formula 3),
T.sub.1(H1)>T.sub.1(H2)  (Numerical Formula 3).

An organic electronic device includes an anthracene-based compound represented by formula (I)

##STR00001## wherein Q is selected from groups represented by formula (A-1) and formula (A-2):

##STR00002## X is O or S; each of R.sub.1, R.sub.2, and R.sub.3 is independently selected from H, -D, a C.sub.1-C.sub.6 alkyl group, a phenyl group, a biphenyl group, a phenyl group substituted by a C.sub.1-C.sub.6 alkyl group, and a biphenyl group substituted by a C.sub.1-C.sub.6 alkyl group; each of L.sub.1 and L.sub.2 is independently selected from a single bond, a phenyl group, a biphenyl group, a phenyl group substituted by a C.sub.1-C.sub.6 alkyl group, and a biphenyl group substituted by a C.sub.1-C.sub.6 alkyl group; and * indicates a binding site.
