Title:
LAMINATE
Document Type and Number:
Japanese Patent JP2022185418
Kind Code:
A
Abstract:
To provide a laminate comprising a linear polarizing light layer, a first adhesive layer, a liquid crystal coating layer, and a second adhesive layer which are laminated in this order, wherein, even if repeated bending is carried out with the linear polarizing layer-side being the inside or repeated bending is carried out with the linear polarizing layer-side being the outside, cracking does not easily occur.SOLUTION: A laminate comprises a linear polarizing light layer, a first adhesive layer, a liquid crystal coating layer, and a second adhesive layer which are laminated in this order. When the storage modulus of the first adhesive layer at a temperature of 25°C is defined as G'1 [kPa], and the storage modulus of the second adhesive layer at a temperature of 25°C is defined as G'2 [kPa], (1) G'1≥1000 kPa and G'2≤50 kPa or (2) G'1≤50 kPa and G'2≥1000 kPa is satisfied.SELECTED DRAWING: None
