    • 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.
    • 本发明涉及使用光弹性系数为-40×10-12Pa-1〜40×10-12Pa-1的聚酯的延迟膜。 本发明还涉及含有磷化合物,脂环族成分和芴衍生物成分作为成分的光学用聚酯树脂,并且满足下列等式(6)和(7):<?在线式 描述=“在线公式”end =“lead”?> 100°C <=玻璃化转变温度<= 150°C(6)<?in-line-formula description =“In-line Formulas”end = “tail”?> <?in-line-formula description =“In-line Formulas”end =“lead”?>和<?in-line-formula description =“In-line Formulas”end =“tail”?> <?in-line-formula description =“In-line Formulas”end =“lead”?> 1.0 <=(Ma / 2 + Mb + Mc)/ P <= 5.0(7) description =“In-line Formulas”end =“tail”?>其中Ma是1吨聚酯树脂中含有的碱金属元素的摩尔数,Mb是包含在碱性金属元素中的碱金属元素的摩尔数 1吨聚酯树脂,Mc是锌元素(Zn),钴元素(Co)和人的摩尔数之和 1吨聚酯树脂中含有的甘油元素(Mn),P是1吨聚酯树脂中含有的磷元素的摩尔数。
