A method of manufacturing a polarizing film having a bleached pattern formed thereon, comprising the steps of:
- (1) heating a polarizing film;
- (2) bleaching the heated polarizing film by discharging an ink composition through an inkjet head of an inkjet printer;
- and
- (3) neutralizing the bleached polarizing film,
- wherein the ink composition is discharged in an amount of 0.02 to 0.5 ml/cm2 per unit area of the heated polarizing film in the step (2).
