Abstract

PURPOSE:To completely prevent a flow to a polarization plate, by sticking the first surface protective film having the first adhesive agent whose adhesion is specific, and the second surface protective film having the second adhesive agent, on one surface of the polarization plate. CONSTITUTION:On the other surface of a polarization plate 2, which release paper 4 has been stuck to one surface through an adhesive agent 3, the first surface protective film 11 having the first adhesive agent 10 which has adhesion even at such a high temperature as adhesion of the second adhesive agent 20 is gone, and has weaker adhesion than that of the adhesive agent 20 at a low temperature, and the second surface protective film 21 having the second adhesive agent 20 are stuck. Subsequently, the release paper 4 is peeled off, the adhesive agent 3 of the polarization plate 2 is stuck onto a liquid crystal display cell 1, and when the films 11, 21 are peeled off, only the film 21 is peeled off by sticking a peeling tape 31 having an adhesive agent 30 whose cohesion and adhesion are sufficiently larger than those of the adhesive agents 10, 20, and peeling off at a high temperature, and both the film 11, 21 are peeled off by peeling off at a low temperature.
