Abstract
Nip rollersandeach including a pair of upper and lower rollers are disposed on an upstream side and a downstream side with a portion to be cut of an optical film F located therebetween. In the nip roller, a center axis C of the upper rolleris displaced relative to a center axis L of the drive rollerin a direction away from the portion to be cut. Upon cutting of the polarizing film F, the upper rollersandare simultaneously moved downward, so that a timing at which the downstream nip rollernips the polarizing film F is delayed. Further, the nip rollerpulls the polarizing film F in the direction away from the portion to be cut, so that tension is applied to the polarizing film F. In this state, the polarizing film F is cut by a laser device
