发明名称 POLARIZING PLATE HAVING HIGH ELASTICITY ADHESIVE LAYER AND IMAGE DISPLAY DEVICE USING THE SAME
摘要 <P>PROBLEM TO BE SOLVED: To provide a polarizing plate having reduced thermal ununiformity in an image display region. <P>SOLUTION: The polarizing plate obtained by laminating a transparent protective layer on one surface of a polarizer comprising a polyvinyl alcohol based resin film, laminating a first adhesive layer directly laminated on the other surface and laminating a transparent polymer film and a second adhesive layer on the first adhesive layer in this order, is provided. In such a case, the first adhesive layer has 0.15-10 MPa storage modulus in a range of 23-80&deg;C. The polarizing plate obtained in this way is used as a rectangular polarizing plate having &ge;7 inch diagonal line length. <P>COPYRIGHT: (C)2010,JPO&INPIT
