A polarizing film provided on the viewing side in an image display device of the present invention, wherein the polarizing film has a polarizer and a first transparent resin layer on the viewing side of the polarizer. The polarizer contains a polyvinyl alcohol-based resin, has a thickness of 10 &#x3bc;m or less, and has, on the side of the first transparent resin layer, a compatible layer which is compatible with the first transparent resin layer and which corresponds to a thickness of 2 to 10% of the thickness of the polarizer. This polarizing film can make it possible to inhibit color phase changes when displaying black, even when a thin-type polarizer is being used.

Polarizing film and image display device

The present invention is a one-side-protected polarizing film having a polarizer and a protective film provided on only one surface of the polarizer, wherein the polarizer contains a polyvinyl alcohol-based resin, has a thickness of 10 &#x3bc;m or less, and is configured so that optical properties represented by a single-body transmittance T and a polarization degree P satisfy the following relationship: P&#x3e;&#x2212;(10&#x2212;1)&#xd7;100 (provided that T&#x3c;42.3) or P&#x2265;99.9 (provided that T&#x2265;42.3), a transparent layer is provided on another surface of the polarizer, and a dynamic friction coefficient of the surface on which the protective film is provided is 0.2 or less. In this one-side-protected polarizing film, it is possible to resist the occurrence of through cracks and nano-slits even when the polarizer has specific optical properties and a thickness of 10 &#x3bc;m or less.

One-side-protected polarizing film, pressure-sensitive-adhesive-layer-attached polarizing film, image display device, and method for continuously producing same

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 &#x3bc;m 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 (&#x3bc;m) between the virtual center plane f and the surface protective film, and a distance y (&#x3bc;m) between the virtual center plane f and the release film satisfy a formula x&#x2212;y&#x3e;&#x2212;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.

Optical film, peeling method, and method for manufacturing optical display panel
