PREPARING METHOD FOR POLARIZER HAVING LOCALLY DEPOLARIZIED AREA, POLARIZER AND POLARIZING PLATE MANUFACTURED BY USING THE SAME

摘要

The present invention relates to a manufacturing method for a polarizer and a polarizer manufactured by using the same. The manufacturing method for a polarizer comprises: a step of preparing a polyvinyl alcohol polarizer dyed with at least one among iodine and a dichromatic dye; and a step of locally bringing an area of the polarizer into contact with a decolorizing solution comprising 1 to 30 wt% of a decolorant to form a depolarized area whose unit transmittance at a wavelength range of 400 to 800 nm is 80% or higher.
