Title:

POLARIZING PLATE WITH RETARDATION LAYER AND IMAGE DISPLAY DEVICE

Document Type and Number:

Japanese Patent JP2023176699

Kind Code:

A

Abstract:

To provide a polarizing plate with a retardation layer having improved durability in a high temperature and high humidity environment.SOLUTION: A polarizing plate with a retardation layer includes: a polarizing plate including a polarizer; a first adhesive layer; a first retardation layer; a second adhesive layer; a second retardation layer; and an adhesive layer in this order. Sticking force between the first retardation layer and the second retardation layer is 0.5 N/25 mm or more. A tensile modulus at 23°C of the second adhesive layer is 1.0×109 Pa or more. A storage modulus at 110°C of the adhesive layer is 5.0×104 Pa or more.SELECTED DRAWING: Figure 1
