It is an object of the invention to provide a polymer compound that, when used in a light-emitting device, results in excellent luminance life for the obtained light-emitting device. The invention provides a polymer compound comprising a constitutional unit represented by formula (1).n n [In formula (1), R 1A , R 1B , R 2A , R 2B represent an unsubstituted alkyl group, R 3 and R 4 represented an unsubstituted or substituted alkyl group, an unsubstituted or substituted alkoxy group, an unsubstituted or substituted aryl group, an unsubstituted or substituted aryloxy group, an unsubstituted or substituted heterocyclic group, an unsubstituted or substituted silyl group, a halogen atom, an alkoxycarbonyl group, a carboxyl or a cyano group, and R 5 and R 6 represent an unsubstituted or substituted alkyl group, an unsubstituted or substituted alkoxy group or an unsubstituted or substituted aryl group. The letters a, b, c and d each represent an integer of 0 to 3. When multiple R 3 , R 4 , R 5 and R 6 groups are present, they may be the same or different.] |
