Abstract: A display unit includes a display panel and a first protective sheet. The display panel has a light-emitting surface. The first protective sheet is provided on the light-emitting surface. The first protective sheet provided in the display unit includes a first impact dispersion layer, a first strain relaxation layer, and a gel-like first impact absorption layer. The first impact dispersion layer has a pencil hardness of 3H or higher. The first strain relaxation layer has flexural strength and tensile strength both higher than the flexural strength and the tensile strength of the first impact dispersion layer. The gel-like first impact absorption layer has a thickness of a submillimeter order or more. The first impact absorption layer, the first strain relaxation layer, and the first impact dispersion layer are arranged in this order from the light-emitting surface.
