Abstract
A display includes a display panel, a shock dispersion layer, a strain relaxation layer, and a shock absorption layer. The shock dispersion layer is provided on a light-extraction side of the display panel and has a Young's modulus of 50 GPa or greater. The strain relaxation layer is provided between the shock dispersion layer and the display panel and has a Young's modulus lower than the Young's modulus of the shock dispersion layer. The shock absorption layer is provided between the strain relaxation layer and the display panel and has a storage modulus of 10 kPa or greater and 1 MPa or less at a room temperature.
