Abstract
A polymer compound that, when used for fabrication of a light emitting device, results in an excellent luminance lifetime for the obtained light emitting device. A polymer compound comprising a constitutional unit represented by formula (1).(In the formula, R1 and R2 each independently represent an unsubstituted alkyl group. R3 and R4 each independently represent a group other than an unsubstituted alkyl group. R5 and R6 each independently represent an unsubstituted or substituted alkyl, unsubstituted or substituted alkoxy or unsubstituted or substituted aryl group. The letters a and b each independently represent an integer of 0-4. The letters c and d each independently represent an integer of 0-3. When multiple R3, R4, R5 and R6 groups are present, they may be the same or different.)
