  • Patent number: 10784451
    Abstract: A flexible laminate, in which it is possible to achieve both flexibility and durability, is disclosed. A flexible display using the flexible laminate is also disclosed. The flexible laminate includes one or more units of a laminate structure in which two hard layers interposing one or more intermediate layers therebetween are bonded together as one unit. The intermediate layer has viscoelasticity. When the flexible laminate is bent, a neutral plane is formed in each inner portion of the hard layers that are bonded together to interpose the intermediate layer therebetween.
