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.
本发明涉及一种树脂组合物,其中包括具有二价寡聚芴作为重复单元的聚合物,其中二价寡聚芴包含至少两个芴单元,可选地具有取代基,并且芴单元的9位碳原子通过直接键或通过可选具有取代基的烷基、芳基或芳基烷基相互结合。在450nm波长(Re450)和550nm波长(Re550)下测得的减速比之比(Re450/Re550)符合以下公式(2):Re450/Re550≦1.0。
