Stacked Body For Display Device And Display Device

Abstract: The present disclosure provides a display device laminate that includes: a first layered film that includes a first resin base material and a first functional layer; a bonding layer that is provided on the surface of the first layered film on the first resin base material side; and a second layered film that is provided on the surface of the bonding layer on the reverse side from the first layered film and includes, in order from the bonding layer side, a second functional layer and a second resin base material. The first layered film and the bonding layer can be peeled from the second layered film, the thickness of the first functional layer is at least 8 µm, the A1 value calculated from A1=E1×h13/12 is at least 0.10×10-3 Pa·m3 but no more than 0.52×10-3 Pa·m3, and the A2 value calculated from A2=E2×h23/12 is no more than 0.07×10-3 Pa·m3. In the expressions, E1 is the tensile elastic modulus (Pa) of the first layered film, h1 is the thickness (m) of the first layered film, E2 is the tensile elastic modulus (Pa) of the second layered film, and h2 is the thickness (m) of the second layered film.
