Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing an elongate polarizer plate, comprising a step of forming, on an elongate substrate, an elongate polarization film having an absorption axis in a direction of 45°±15° relative to the longitudinal direction of the elongate substrate, wherein the elongate polarization film is formed from a second dried layer. 2. The method for producing an elongate polarizer plate according to claim 1 , further comprising a step of…
