A double-sided pressure-sensitive adhesive-layer-attached polarizing film has a polarizing film nearest to a viewer-side of an image display device among at least one polarizing film, a pressure-sensitive adhesive layer A located on the viewer-side, 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 layers A and B are equipped with separators SA and SB, respectively. 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. 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.
