摘要： A pressure-sensitive adhesive and retardation layer-attached polarizing plate (4) of the invention comprises a retardation layer-attached polarizing plate (3) comprising a polarizing plate (2) that comprises an iodine-based polarizer (1) and a transparent protective film laminated on both sides of the polarizer (1); and a retardation layer provided on at least one of the transparent protective films; and an acrylic pressure-sensitive adhesive layer laminated on the retardation layer side of the retardation layer-attached polarizing plate (3), wherein the iodine-based polarizer (1) has a ratio (K/I), which is the content (% by weight) of potassium (K) to the content (% by weight) of iodine (I) in the polarizer, of 0.200 to 0.235, the polarizing plate (2) comprises the iodine-based polarizer (1) and the transparent protective film laminated with an adhesive layer formed from a water-soluble adhesive containing an acetoacetyl group-containing polyvinyl alcohol resin and a crosslinking agent, the retardation layer-attached polarizing plate (3) has a measured dimensional shrinkage of 0.5% or less in the direction of its absorption axis after it is allowed to stand at 80° C. for 24 hours, the pressure-sensitive adhesive and retardation layer-attached polarizing plate (4) has a single-piece transmittance of 41.0% to 43.2%. The pressure-sensitive adhesive and retardation layer-attached polarizing plate can resist a change in optical properties and keep visibility high, even under heated or humidified conditions.
