Abstract: A method for manufacturing an image display, includes: preparing a roll of a long sheet of a pressure-sensitive adhesive polarizing plate comprising a polarizer (P), a transparent protective film (E) provided on only one side of the polarizer (P) with an adhesive layer (G) interposed therebetween, and a pressure-sensitive adhesive layer (B) provided on another side of the polarizer (P) with a protective layer (H) having a tensile modulus of 100 MPa or more interposed therebetween; cutting the pressure-sensitive adhesive polarizing plate into a predetermined size, while feeding the sheet from the roll; and bonding the pressure-sensitive adhesive polarizing plate to an optical display unit with the pressure-sensitive adhesive layer (B) interposed therebetween after the cutting step.
