Patent ID: 7022204

Claim:
A polarizing plate bonding method, comprising: a step of cutting at least a polarizing plate and an adhesive layer of a strip-shaped film, composed of said polarizing plate, a direction of an axis of light transmission of which is oriented obliquely relative to a longitudinal direction of said strip-shaped film, and a release film bonded to said polarizing plate, with interposition of said adhesive layer, when a forward end side severed end face of said strip-shaped film perpendicular to the longitudinal direction of said strip-shaped film has traveled a length corresponding to a length of a substrate, to form a film piece so as to leave the release film uncut, a step of separating said release film from the film piece severed by said cutting, and a step of bonding a tacky surface of said film piece freed of said release film to a mating position of said substrate so that a forward end side end face of the transported substrate is parallel to the pre-severed end face of said film piece while said film piece and said substrate are moved to the same direction so that the supply of said film piece is synchronized with the transport of said substrate.
