Abstract: A laminate includes a shock absorbing layer, a support, and a hard coat layer, in which the shock absorbing layer has a maximum value of tan δ in a frequency range of 104 to 1013 Hz at 25° C. The tan δ is a ratio of a loss modulus with respect to a storage modulus.

Abstract: A liquid crystal panel and an image display device include a front-side polarizing plate in which a resin film, a shock absorbing layer, and a hard coat layer are disposed in this order; and a rear-side polarizing plate in which a resin film and a shock absorbing layer are disposed in this order, in which a storage elastic modulus E′f of the shock absorbing layer of the front-side polarizing plate at 25° C. and a frequency of 106 Hz is more than 1 GPa, and a relationship between the E′f and a storage elastic modulus E′r of the shock absorbing layer of the rear-side polarizing plate at 25° C. and a frequency of 106 Hz satisfies the expression E′f−E′r>0.
