POLARIZING PLATE, METHOD FOR MANUFACTURING SAME, AND METHOD FOR MANUFACTURING DISPLAY DEVICE

This polarizing plate is obtained by laminating a polarizer, a first protective film disposed on one surface of the polarizer, a second protective film disposed on the other surface of the polarizer, and a release film disposed on the surface of the first protective film on the opposite side from the polarizer. The second protective film has a light absorption coefficient A2 of 1.0 * 102 to 4.5 * 102/[mu] m for light having a wavelength of 9.4 [mu] m. In a cross section of the polarizing plate along the lamination direction, the inclination angle phi of a straight line connecting an end point P1 on the opposite side of the peeling film from the first protective film and an end point P2 on the second protective film side of the polarizer in the cut end face is 0.5-10 degrees with respect to the lamination direction. 本发明的偏振片是将起偏器、在其一面配置的第1保护膜、在另一面配置的第2保护膜、及在第1保护膜的与起偏器相反侧的面配置的剥离膜层叠而成。第2保护膜的波长9.4μm的光的吸光系数A2为1.0×102～4.5×102/μm。在偏振片的沿着所述层叠方向的截面中，将切断端面中的剥离膜的与第1保护膜相反侧的端点P1与起偏器的第2保护膜侧的端点P2连接的直线的相对于所述层叠方向的倾斜角度φ为0.5～10°
