Abstract:
There is provided a method for manufacturing a liquid crystal panel comprises the steps of:(Step A1) manufacturing a polarizing film including a laminate composed of a first base film and a polarizing thin layer, the step including: applying a vinyl alcohol-based polymer on a surface of the first base film to form a vinyl alcohol-based polymer thin layer; and wet dyeing the vinyl alcohol-based polymer thin layer after stretching the thin layer together with the first base film to obtain a polarizing thin layer, and(Step B1) adhering the polarizing film without an adhesion layer during storage and transportation at least to one surface of a liquid crystal cell through an adhesion layer in a liquid crystal panel manufacturing process.
