PROBLEM TO BE SOLVED: To provide a tacky optical film bearing a tacky layer for sticking the film on the glass substrate of a liquid crystal panel, good in reworkability through suppressing the rise in its adhesive force with time or even under heating after laminated on the glass. SOLUTION: This tacky optical film is such that one side of an optical film is laminated with a tacky layer for sticking the film on the glass substrate of a liquid crystal panel; wherein it is characteristic that the ratio of the storage modulus (A) of the tacky layer at 20 deg.C to that (B) at 100 deg.C:A/B is <=1.5. |
