PROBLEM TO BE SOLVED: To provide an adhesion polarizing plate thinner than before with little deterioration of the display quality under the elevated temperature and high humidity environment. SOLUTION: A triacetyl cellulose film of 45 μm thickness is stuck together by using a polyvinyl alcohol adhesive as a protective layer on both sides of a polarizer of 25 μm thickness made of a uniaxial stretching polyvinyl alcohol film, an acryl based pressure sensitive adhesive mixed with isocyanate based cross-linking material in an organic solvent (toluene) in this one side is applied by 25 μm thickness (thickness at the time of drying) by a roll coater, and the adhesion polarizing plate whose shear modulus in the adhesive layer is 6×109 Pa is obtained. |
