Abstract
The present invention is a sheet-like optical film including a release film, a first pressure-sensitive adhesive layer, a polarizing film, and a surface protective film, laminated in this order; wherein a thickness of the polarizing film is 60 μm or less, and when a virtual center plane f is a virtual plane located at an intermediate position in total thickness of the optical film, a distance x (μm) between the virtual center plane f and the surface protective film, and a distance y (μm) between the virtual center plane f and the release film satisfy a formula x−y>−20. The sheet-like optical film of the present invention enables the release film to be easily peeled even if a thin polarizing film is used.
