WIPO Patent Application WO/2024/018992
Kind Code:
A1
Abstract:
[Problem] To provide a polarizing laminate having a reduced optical distortion when measured with MIL-DTL-43511D. [Solution] Provided is a polarizing laminate which comprises a polarizing film comprising a uniaxially stretched polyvinyl alcohol-based resin film and transparent protective layers respectively arranged on both surfaces of the polarizing film each through an adhesive layer, in which the difference between a maximum value and a minimum value of the width of a gap between two slits adjacent to the polarizing laminate (i.e., a slit interval) in an optical distortion measured with MIL-DTL-43511D is 1.05 mm or less.
