摘要： The invention relates to an optical film containing aromatic polymer which shows high solubility to solvents, and methods for production thereof. Further, the invention also relates to an optical laminate, a polarizing plate, and an image display device each using the optical film. The optical film may be attained by using polyester with a specific structure. The polyester with a specific structure may be obtained by condensation polymerization of bisphenol compound(s) and dicarboxylic acid compound(s) with biphenyl structure, and preferably has no halogen atom in its chemical structure. The optical film of the invention advantageously has not only high solubility in solvents but also a high level of heat resistance and birefringence producing capability. When the content of the biphenyl structure is high, the optical film of the invention can also have large wavelength dispersion of birefringence.
