FABRICATION METHOD OF IODINE TYPE POLARIZER WITH HIGH TRANSMISSIVITY AND DRAW RATIO, POLARIZER AND OPTICAL FILTER FOR FLAT PANEL DISPLAY USING THE SAME

摘要

The invention goyeon high transmittance production method for an iodine-based polarizer having a mystery, the polarizer and the first and the second stretching step the one relates to an optical filter, the stretching in the process for producing an iodine polarizer in more detail the process having the same the polarizer of the present invention relates to manufacturing the first high-temperature dry interval stretching process carried out in two steps, and (dry-Heating zone drawing) and the second wet-stretching method for manufacturing a polarizer for performing a process, and therefrom. ; And by the present invention by performing a stretching zone for applying a momentary high temperature in local areas of the base material film reduces the residual stress of the base film and facilitate the control of the stretch ratio without breaking, wherein the polarizer is provided with the polarizing film of single or multiple features by laminating the optical film is preferably applied to an optical filter for flat panel displays. ; Hot stretching zone, second step stretching process, the residual stress, the stretching ratio, high transmittance, the display device
