Abstract

The present invention relates to a method for fabricating a polarizer, and more particularly, to a method for fabricating a polarizer which includes a cross-linking operation of immersing a polyvinyl alcohol-based film in a cross-linking aqueous solution containing a compound having an aldehyde group and a carboxy group. Accordingly, the film has excellent optical characteristics, and is prevented from being torn and wrinkled. In addition, the area of the film can be increased, and the thickness thereof can be decreased. Furthermore, the polarizer is highly stable dimensionally in the width and longitudinal directions thereof. Moreover, the characteristic odors of aldehydes are offset to thereby improve processability and productivity.
