Provided is a process for manufacturing a polarizing laminate film having a small film thickness and high performance. A process for manufacturing a polarizing laminate film comprising a base film and a polarizer layer formed on one surface of the base film, which comprises a resin layer formation step, a stretching step and a dyeing step in this order, wherein the resin layer formation step comprises forming a resin layer containing a polyvinyl alcohol resin on one surface of the base film to produce a laminate film, the stretching step comprises carrying out the free-end uniaxial stretching of the laminate film, and the dyeing step comprises dyeing the resin layer in the laminate film with a dichroic dye to form the polarizer layer, and wherein the width (W1) of the laminate film that is not subjected to the free-end uniaxial stretching yet and the width (W2) of the laminate film that has been subjected to the free-end uniaxial stretching fulfill the relationship represented by formula (1). (W1-W2)÷W1×100 = 40 Formula (1) |
