積層体及び画像表示装置
Document Type and Number:
Japanese Patent JP7307754
Kind Code:
B2
Abstract:
To provide a flexible laminate which comprises a front plate and a circularly polarizing plate having an adhesive layer provided on both surfaces thereof, where the laminate produces little swelling generated on a bent portion of a front plate-side surface and provides superior visibility even after the laminate is left for a long period of time in a state where the front plate side is bent on the inside in high-temperature high-humidity environment, and to provide an image display device having the same.SOLUTION: A laminate 100 comprises a front plate 10 and a circularly polarizing plate 20 with an adhesive layer on both surfaces thereof. The laminate satisfies [(b/a)×c]≥2200, where a [μm] represents thickness of the front plate, b [μm] represents thickness of the circularly polarizing plate with the adhesive layer on both surfaces, and c [MPa] represents moisture resistance thermal modulus of the front plate with temperature of 60°C and relative humidity of 90%RH.SELECTED DRAWING: Figure 1
