摘要

A polymer compound comprising at least one repeating unit of formula (1) or formula (2), <CHEM> wherein Ar1 to Ar4 each independently represent an arylene group or a divalent heterocyclic group; E1, E2, and E3 represent an aryl group (A) having three or more substituents, or a heterocyclic group (B) having one or more substituents, and the total number of substituents and hetero atoms of the heterocyclic ring is three or more; a and b represent 0 or 1, and 0 <=a+b<=1, <CHEM> wherein Ar5 to Ar11 each independently represent an arylene group or a divalent heterocyclic group; E4 to E9 represent an aryl group or a monovalent heterocyclic group; l, m and n represent 0 to 2; o and p represent 0 or 1, and l+m+n+o+p is 2 or more.
