An anthracene derivative, an organic light emitting layer prepared from the derivative, and an organic electroluminescent device containing the organic light emitting layer are provided to improve color purity, luminous efficiency, brightness, power efficiency and heat resistance. An anthracene derivative is represented by the formula 1 or 2. In the formula 1, Ar1 to Ar5 are identical or different one another and are independently H, or a substituted or unsubstituted aromatic group derived from the compound selected from the group consisting of benzene, biphenyl, anthracene and phenanthrene. In the formula 2, Ar1 to Ar4 are identical or different one another and are independently H, or a substituted or unsubstituted aromatic group derived from the compound selected from the group consisting of benzene, biphenyl, anthracene and phenanthrene; and Ar5 and Ar6 are identical or different each other and are independently a group derived from an aliphatic hydrocarbon, benzene, naphthalene, biphenyl or anthracene.
