Provided are a blue electroluminescent polymer and an organic electroluminescent device using the same. A phenoxazine unit is introduced into a polyarylene main chain, represented by the following chemical formula (1): [Wherein, Ar is a C6-26 aromatic group or a C4-20 heteroaromatic group in which a heteroatom is contained in an aromatic ring, and the aromatic group or heteroaromatic group includes C1 to C26. At least one of 12 alkyl groups, C1-12 alkoxy groups or -N (R ') (R¨) (R' and R¨ are hydrogen or C1-12 alkyl groups independently of one another) X is O, CH 2 or S, and R is a hydrogen atom, or a C1-12 linear alkyl group, a C1-12 branched alkoxy group or a C3-12 cyclic alkyl group, or a C6-14 An aromatic group, wherein the aromatic group is a C1-12 alkyl group, an alkoxy group or -N (R ') (R¨) (R' and R¨ are hydrogen or C1-12 alkyl Group) can be substituted one or more times, and n is 0.0 To the organic electroluminescent device having an organic layer containing the blue electroluminescent polymer and the polymer represented by a real number of 0.99.
