Title:
POLARIZING PLATE AND IMAGE DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2022077996
Kind Code:
A
Abstract:
To provide a polarizing plate which can improve the occurrence of leak light by controlling the deflection characteristics of a large-sized panel without a reverse curling phenomenon.SOLUTION: A polarizing plate comprises: a polarizer 110; and a surface treatment film 120 laminated on one surface of the polarizing plate 110. The surface treatment film includes a (meth)acrylic film as a base film 121 and satisfies 70≤a×b/c≤300. Here, a is the thickness (μm) of the base film, b is the tensile strength (Mpa) of the polarizing plate and c is the moisture vapor permeability (g/m2/24hr) of the surface treatment film. There is also provided an image display device having the polarizing plate.SELECTED DRAWING: Figure 1
