Polarizing film with added adhesive layer, polarizing film with added adhesive layer for in-cell liquid crystal panel, in-cell liquid crystal panel, and liquid crystal display device

A pressure-sensitive adhesive layer attached polarizing film for an in-cell type liquid crystal panel, which comprises an in-cell type liquid crystal cell that is provided with a liquid crystal layer comprising liquid crystal molecules which are homogeneously aligned in the absence of an electric field, a first transparent substrate and a second transparent substrate sandwiching the liquid crystal layer on both sides, and a touch sensing electrode unit related to a touch sensor and touch-driven functions disposed between the first transparent substrate and the second transparent substrate, and which is disposed on a viewing side of the in-cell type liquid crystal cell, wherein:

• the pressure-sensitive adhesive layer of the pressure-sensitive adhesive layer attached polarizing film is disposed between the polarizing film of the pressure-sensitive adhesive layer attached polarizing film and the in-cell type liquid crystal cell,
• the polarizing film comprises at least a polarizer and a transparent protective film,
• at least the polarizing film, an anchor layer, and the pressure-sensitive adhesive layer are provided in this order from the viewing side,
• the anchor layer includes a conductive polymer,
• a surface resistance value of the anchor layer is from 1.0×108 to 1.0×1011Ω/□, and
• a moisture permeability of the transparent protective film at 40° C.×92% RH is 10 g/(m2·24 h) or more.
