Title: POLARIZING PLATE HAVING LOCAL DEPOLARIZATION AREA AND METHOD FOR MANUFACTURING SAME
Abstract:
The present invention relates to a polarizing plate having a depolarization area and a method for same, the polarizing plate comprising a polyvinyl alcohol-based polarizer dyed with iodine and/or a dichroic dye, wherein group permeability of the local depolarization area is 70% at a wavelength range from 400nm to 800nm, by irradiating on a portion of the polarization plate a light having a specific wavelength selected from a wavelength range from 200nm to 800nm.
