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.

Abstract: A display includes a display panel and a first protection sheet. The display panel has flexibility and a light output face. The first protection sheet is provided on the light output face and includes a first shock dispersion layer, a first strain relaxation layer, and a first shock absorption layer. The first shock dispersion layer includes a flexible reinforced-glass member, a flexible hard-coat film, or a flexible double-sided hard-coat film. The first strain relaxation layer includes a wet-laminated layer or a dry-laminated layer that is in close contact with a surface of the first shock dispersion layer adjacent to the display panel. The first shock absorption layer includes a gel layer having a thickness of submillimeter order or greater. The first shock absorption layer, the first strain relaxation layer, and the first shock dispersion layer are laminated in this order from the light output face of the display panel.
