Abstract
A polymer includes a structural unit represented by Chemical Formula 1 and an organic layer composition including the same.wherein in Chemical Formula 1, A is a carbon cyclic group including at least one hetero atom, B is one of groups in Group 1, where Ar1 to Ar4, R11 to R14, L and m are as defined in the specification and * is a linking point. When the carbon cyclic group includes at least two hetero atoms when the carbon cyclic group includes a pentagon cyclic moiety and the pentagon cyclic moiety includes a nitrogen atom (N) as a hetero atom, and the at least two hetero atoms are the same or different:
