| titleOfInvention | Optical film, method for producing same, polarizer and liquid crystal display device |
| abstract | assignment And the homogeneity of the film thickness is improved so that the fluctuation of the retardation in the in-plane direction accompanying the change of the environmental humidity is suppressed, and a production method thereof. Solution An optical film having a film thickness of 20 to 60 占 퐉 and satisfying the expressions (1) to (3). (1) PV (whole surface) ≤ 0.5 ㎛ 2.5? PV (MD) / PV (TD)? 0.8 (3) ΔRe (30 - 80) <3 nm (PV (MD) is the average value of 10 points of the entire surface PV value, which is the difference between the maximum value and the minimum value of the film thickness at all points within each circular area, PV (TD) represents the average value of ten points of the length PV that is the difference between the maximum value and the minimum value of the film thickness at all points on the film (30%) at a relative humidity of 30% and Re (80%) at a relative humidity of 80%, which is an average value of 10 points of the width PV value which is a difference between the maximum value and the minimum value of the thickness; %)) |
