Method for manufacturing polarizing film using ultrasonic vibrator for atomizing coating solution

摘要

Disclosed herein are a polarizing film manufacturing method including (a) injecting a coating solution containing a component functioning as a polarizer into a sealed chamber to form an injection condition of the coating solution, (b) supplying a polyvinyl alcohol film into the chamber and dyeing outer surfaces of the polyvinyl alcohol film with the coating solution, and (c) discharging the polyvinyl alcohol film dyed with the coating solution out of the chamber, a polarizing film manufacturing apparatus, and a polarizing film exhibiting improved optical properties manufactured using the same.
