Double-sided pressure-sensitive-adhesive-layer-attached polarizing film, and image display device

A double-sided pressure-sensitive adhesive-layer-attached polarizing film, comprising a polarizing film nearest to a viewer-side of an image display device among at least one polarizing film used in the device, a pressure-sensitive adhesive layer A located on the viewer-side of the polarizing film, and a pressure-sensitive adhesive layer B on a side of the polarizing film that is opposite to the pressure-sensitive adhesive layer A, the pressure-sensitive adhesive layer A being equipped with a separator SA and the pressure-sensitive adhesive layer B being equipped with a separator SB;

• wherein the polarizing film is a single-side protected polarizing film having a polarizer of 15 μm or less thickness and having a transparent protective film on only a single side of the polarizer, and the pressure-sensitive adhesive layer B is located on the polarizer side of the single-side protected polarizing film;
• the pressure-sensitive adhesive layer A has a thickness of 25 μm or more;
• and
• the pressure-sensitive adhesive layer B has a thickness of 25 μm or less.
