摘要： PROBLEM TO BE SOLVED: To provide an adhesive optical member which does not cause optical abnormalities such as uneven luminance. SOLUTION: The adhesive optical member is obtained by covering an adhesive layer 3 disposed on an outermost surface of one side or both sides of an optical member 2 having at least a polarizing plate or a retardation plate by temporary adhesion with a stripping surface of a separator 4 obtained by surface-treating a polyester film comprising a PET film in which the content of a low molecular oligomer having a molecular weight of ≤1,000 is confined to ≤1.2 wt.% with a stripping agent. The generation of transparent crystals in the adhesive layer due to the migration of a separator forming component can be prevented, consequently the occurrence of bright spots, etc., due to abnormality in refractive index can be prevented.
