METHOD FOR PRODUCING ELONGATE POLARIZER PLATE

摘要

The present invention provides a method for producing an elongate polarizer plate having an absorption axis in a direction of 45°±15° relative to the longitudinal direction of the elongate polarizer plate. Provided is a method for producing a polarizer plate including a step of forming, on an elongate substrate, an elongate polarization film having an absorption axis in a direction of 45°±15° to the longitudinal direction of the elongate substrate. The above-mentioned production method further includes a step of forming, on an elongate substrate, an elongate orientation film having an orientation regulating force direction of 45°±15° to the longitudinal direction of the elongate substrate, and can perform the elongate orientation film formation step and the elongate polarizer plate formation step in this order.
