Abstract
A method of producing an optical film laminate includes: stretching and dyeing a laminate including a resin substrate and a polyvinyl alcohol-based resin layer formed on one side of the resin substrate to produce a polarizing film on the resin substrate; laminating a first protective film on the polarizing film on an opposite side to the resin substrate; and peeling the resin substrate, followed by laminating a second protective film on the polarizing film on a side from which the resin substrate has been peeled. The first protective film is a protective film to be placed on an optical cell side when the optical film laminate is attached to the optical cell, the second protective film is a protective film to be placed on an opposite side to the optical cell when the optical film laminate is attached to the optical cell.
