A method of quantifying whether an adhesive agent leaks from a polarizing plate and/or a degree of leakage of the adhesive agent according to an exemplary embodiment of the present invention, including: (a) preparing a polarizing plate including an adhesive layer; (b) providing the polarizing plate so that one end of the polarizing plate adjoins a guide unit; (c) moving the polarizing plate on the guide unit; (d) measuring frictional force applied between the polarizing plate and the guide unit while moving the polarizing plate; (e) deriving a determination criterion based on the measured value of the frictional force, and (f) determining whether the adhesive agent leaks from the polarizing plate and/or the degree of leakage of the adhesive agent based on the determination criterion.

Method for detecting adhesive agent leak from polarizing plate and method of quantifying degree of leakage

A method of deriving an appropriate condition for cutting a polarizing plate, the method including: (a) preparing a polarizing plate including an adhesive layer and having a cut surface; (b) providing the polarizing plate so that one end of the polarizing plate adjoins a guide unit; (c) moving the polarizing plate on the guide unit; (d) measuring frictional force applied between the polarizing plate and the guide unit while moving the polarizing plate; and (e) deriving the appropriate condition for cutting the polarizing plate based on the measured value of the frictional force and a predetermined adhesive agent leakage determination criterion based on the frictional force.
