Abstract
A flexible laminate for which increased flexibility and improved durability can coexist, and a flexible display provided with same, are disclosed. The flexible laminate has at least one unit of a laminated structure in which two hard layers closely adhere to each other with at least one intermediate layer therebetween. When the flexible laminate is bent, neutral planes are formed inside each of the hard layers that closely adhere to each other with the intermediate layer therebetween. The flexible laminate satisfies the following expression: a×ln(tan δ×E/0.01)≥100. In the expression, a is any value ranging from 200 to 2,000, tan δ represents a loss factor for a substance configuring the intermediate layer, and Erepresents an elastic modulus (MPa) of the substance configuring the intermediate layer.
