摘要： The present invention relates to a retardation film using polyester having a photoelastic coefficient of −40×10−12 Pa−1 to 40×10−12 Pa−1. The present invention also relates to a polyester resin for optical use which contains a phosphorus compound, and an alicyclic component and a fluorene derivative component as constituents, and satisfies the following equations (6) and (7): 100° C.≦glass transition temperature≦150° C.  (6) and 1.0≦(Ma/2+Mb+Mc)/P≦5.0  (7), wherein Ma is the number of moles of an alkali metal element contained in 1 ton of the polyester resin, Mb is the number of moles of an alkaline earth metal element contained in 1 ton of the polyester resin, Mc is the sum of the number of moles of a zinc element (Zn), a cobalt element (Co) and a manganese element (Mn) contained in 1 ton of the polyester resin, and P is the number of moles of a phosphorus element contained in 1 ton of the polyester resin.
