| 摘要 | The invention relates to a resin composition which comprises a polymer having a divalent oligofluorene as a repeating unit therein, wherein the divalent oligofluorene contains at least two fluorene units optionally having a substituent, and the 9-positioned carbon atoms of the fluorene units bond to each other via a direct bond or via an alkylene group optionally having a substituent, an arylene group optionally having a substituent, or an aralkylene group optionally having a substituent, and a ratio of a retardation measured at a wavelength of 450 nm (Re450) to a retardation measured at a wavelength of 550 nm (Re550) satisfies the following formula (2): Re450/Re550≦1.0. | ||

| 主权项 | 1. A resin composition, comprising a polymer having a divalent oligofluorene as a repeating unit, wherein: the divalent oligofluorene contains at least two fluorene units optionally having a substituent; 9-positioned carbon atoms of the fluorene units bond to each other via a direct bond, via an alkylene group optionally having a substituent, via an arylene group optionally having a substituent, or via an aralkylene group optionally having a substituent; and a ratio of a retardation measured at a wavelength of 450 nm (Re450) to a retardation measured at a wavelength of 550 nm (Re550) satisfies formula (2): Re450/Re550<1.0 (2). | ||
