摘要

Disclosed is a polymer compound containing a repeating unit represented by the following formula (1). -[Ar₁-(X₁)_n]- (1) (In the formula, Ar₁ represents an arylene group represented by the formula (2) below or the like; X₁ represents -CR¹=CR²- (wherein R¹ and R² respectively represent a hydrogen atom or a substituent) or -C=C-; and n represents 0 or 1.) (2) (In the formula, Ar₂ represents an arylene group or the like; Ar⁵ represents a direct bond, an arylene group or the like; R³ and R⁴ respectively represent a direct bond, a substituent or the like; Ar₃ and Ar₄ respectively represent an aryl group or the like; and Y represents one of the following formulae. (formulae) In this connection, when Ar₅ represents a direct bond, R³ also represents a direct bond.)
