Abstract
A polymer compound comprising a constitutional unit represented by the following formula (1) and a constitutional unit represented by the following formula (X) and/or a constitutional unit represented by the following formula (Y), [wherein, aand aeach independently represent an integer of 0 or more. Arand Areach independently represent an arylene group or a divalent heterocyclic group and these groups each optionally have a substituent. Arand Areach independently represent an arylene group, a divalent heterocyclic group or a divalent group in which at least one arylene group and at least one divalent heterocyclic group are bonded directly to each other, and these groups each optionally have a substituent. When there are a plurality of Arand a plurality of Ar, each of them may be the same or different. R, Rand Reach independently represent an alkyl group, an aryl group or a monovalent heterocyclic group and these groups each optionally have a substituent. When there are a plurality of Rand a plurality of R, each of them may be the same or different.]Ar  (Y)[wherein, Arrepresents an arylene group, a divalent heterocyclic group or a divalent group in which at least one arylene group and at least one divalent heterocyclic group are bonded directly to each other, and these groups each optionally have a substituent.].
