    • PROBLEM TO BE SOLVED: To provide a polyester resin having both high refractive index and low birefringent properties.
      SOLUTION: The polyester resin includes a dicarboxylic acid component and a diol component as polymerizable components, wherein the dicarboxylic acid component is a dicarboxylic acid component containing an asymmetric monocyclic aromatic dicarboxylic acid component (e.g. an isophthalic acid dicarboxylic acid component) as a main component (e.g. in an amount of more than 50 mol% of the whole dicarboxylic acid components), and the diol component comprises a compound having a 9,9-bis(hydroxy(poly)alkoxyaryl)fluorene skeleton. The diol component may comprise a compound having a 9,9-bis(hydroxy(poly)alkoxyaryl)fluorene skeleton, and an aliphatic diol component.
