    • Disclosed is a method for producing a polarizer, which enables to produce a polarizer which is prevented from formation of curls even when a hydrophilic polymer film is brought into contact with a liquid by a spray treatment. Specifically disclosed is a method for producing a polarizer, which comprises a swelling step A for swelling a hydrophilic polymer film (1) by bringing the film (1) into contact with a swelling liquid (2), a dyeing step B for dyeing the hydrophilic polymer film (1) by bringing the film (1) into contact with a dyeing liquid (3) containing a dichroic substance, and a crosslinking/stretching step C wherein the hydrophilic polymer film (1) is crosslinked by being brought into contact with a crosslinking liquid (3), and then stretched. In this method, contact with the swelling liquid (2) in the swelling step (A) is attained by spraying the swelling liquid (2) onto both sides of the hydrophilic polymer film (1) in a gaseous phase.

    • A process for producing an optical film that has excellent durability, contributing to thickness reduction, and that prevents heat irregularity, satisfactorily avoiding light leakage during black displaying. There is provided a process comprising the steps of applying a coating liquid containing a liquid crystal material to an alignment substrate; aligning the liquid crystal material to thereby form a first optical compensation layer on the substrate surface; transferring the first optical compensation layer to a surface of transparent protective film; superimposing a polarizer on another surface of transparent protective film; and superimposing a second optical compensation layer on the surface of the first optical compensation layer. The polarizer and the first optical compensation layer are disposed on opposite sides of the transparent protective film. The first optical compensation layer and the second optical compensation layer are disposed so that the slow axis of each thereof and the absorption axis of the polarizer make an angle falling within a specified range.
