1. A polymer compound comprising:
a constitutional unit represented by the following formula (1), a constitutional unit represented by the following formula (2), and a constitutional unit represented by the following formula (3) and/or a constitutional unit represented by the following formula (4′);wherein Ar1 and Ar3 each independently represent an unsubstituted or substituted arylene group or an unsubstituted or substituted divalent heterocyclic group;Ar2 and Ar4 each independently represent an unsubstituted or substituted arylene group, an unsubstituted or substituted divalent heterocyclic group, or a divalent group

heterocyclooxy group, a heterocyclothio group, an imine residue, an amide compound residue, an acid imide residue, a carboxyl group, a hydroxyl group, a nitro group or a cyano group;when a plurality of R1 are present, they may be the same or different:at least one R1 substitutes a hydrogen atom that is directly bonded to a carbon atom adjacent to the carbon atom forming a bond with another constitutional unit of the aromatic hydrocarbon group or heterocyclic group;p represents an integer of 1 or greater;wherein na represents an integer of 0 to 3, nb represents an integer of 0 to 12, nA represents 0 or 1 and n represents an integer of 1 to 4;Ar10 represents an unsubstituted or substituted (2+n)-valent aromatic hydrocarbon group or an unsubstituted or substituted (2+n)-valent heterocyclic group;La and Lb each independently represent an unsubstituted or substituted alkylene group or an unsubstituted or substituted phenylene group;when a plurality of La are present they may be the same or different;when a plurality of Lb are present they may be the same or different;LA represents an oxygen atom or a sulfur atom;when a plurality of LA are present, they may be the same or different;Q1 represents a monovalent crosslinkable group;when a plurality of Q1 are present, they may be the same or different;the constitutional unit represented by formula (3) is different from the constitutional unit represented by formula (2);wherein c represents 0 or 1, and d represents an integer of 0 to 4,Ar20 and Ar40 each independently represent an unsubstituted or substituted arylene group or an unsubstituted or substituted divalent heterocyclic group, and Ar30′ represents an unsubstituted or substituted (2+d)-valent aromatic hydrocarbon group, an unsubstituted or substituted (2+d)-valent heterocyclic group, or a (2+d)-valent group having a structure in which two or more identical or different rings selected from among aromatic rings and heterocyclic rings are linked, where the (2+d)-valent group may be substituted;Q2′, Q3′ and Q4′ represent a monovalent crosslinkable group, an unsubstituted or substituted alkyl group, an unsubstituted or substituted aryl group, or an unsubstituted or substituted monovalent heterocyclic group, with the proviso that at least one of Q2′, Q3′ and Q4′ is a monovalent crosslinkable group;when a plurality of Q4′ are present, they may be the same or different;na represents an integer of 0 to 3, nb represents an integer of 0 to 12, and nA represents 0 or 1;La and Lb each independently represent an unsubstituted or substituted alkylene group or an unsubstituted or substituted phenylene group;when a plurality of La are present, they may be the same or different;when a plurality of Lb are present, they may be the same or different;LA represents an oxygen atom or a sulfur atom;when a plurality of LA are present, they may be the same or different;ng represents an integer of 0 to 3, nh represents an integer of 0 to 12, and nD represents 0 or 1;Lg and Lh each independently represent an unsubstituted or substituted alkylene group or an unsubstituted or substituted phenylene group;when a plurality of Lg are present, they may be the same or different;when a plurality of Lh are present, they may be the same or different;LD represents an oxygen atom or a sulfur atom;when a plurality of LD are present, they may be
