The present invention provides a polymer compound comprising a repeating unit represented by the following Chemical Formula 1 and a repeating unit selected from the following Chemical Formulas 2-1 and 2-2.n n n <Formula 1>n n n n n n n n <Formula 2-1>n n n n n n n n <Formula 2-2>n n n n n n n n In the formula, Ar 1 and Ar 2 represent an arylene group or a divalent heterocyclic group. a and b each independently represent 0 or 1, and E 1 , E 2, and E 3 each have an aryl group or three or more substituents selected from an alkyl group and an alkoxy group, or one or more substituents. The monovalent heterocyclic group whose sum of the number of and the number of the hetero atoms of a heterocyclic ring is three or more is shown. Ring A, ring B, ring C and ring D represent an aromatic ring, X represents -O- and -S- and the like, Y represents -C≡C- and the like.n n n Polymer compound, polymer light emitting device, planar light source, light emitting thin film, conductive thin film, organic semiconductor thin film |
