Manufacturing method of polarizing film |
| abstract |
PROBLEM TO BE SOLVED: To produce a polarizing film using a PVA polymer film as a raw film, which can produce a polarizing film having a high limit drawing ratio and capable of producing a polarizing film excellent in optical performance without breaking even when uniaxially drawn at a high magnification. Offer. SOLUTION: Using a PVA polymer film satisfying the following formulas (I) and (II) or a PVA polymer film satisfying the following (I) to (III) as a raw film, dyeing and uniaxial stretching A method for producing a polarizing film by performing a fixing process and a drying process. Δn (MD) Ave −0.1 × 10 −3 ≦ Δn (TD) Ave ≦ Δn (MD) Ave + 0.25 × 10 −3 (I) Δn (TD) Ave ≦ 2.5 × 10 -3 (II) 1.3 × 10 -3 ≦ Δn (MD) Ave ≦ 2.0 × 10 -3 (III) [In the formula, Δn (MD) Ave is a value obtained by averaging the birefringence in the machine flow direction of the PVA polymer film in the film thickness direction, and Δn (TD) Ave is the birefringence in the width direction of the PVA polymer film. A value obtained by averaging the rate in the film thickness direction is shown. ] [Selection figure] None |
