Abstract: The present disclosure relates to display apparatuses and methods for manufacturing the display apparatuses. One example display apparatus includes an array substrate and a laminated structure. The array substrate includes a substrate and an array layer located on a side of the substrate. The laminated structure is located on a side that is of the array layer and that is opposite to the substrate, and includes a first film layer and a second film layer. The first film layer is located on a side that is of the second film layer and that is opposite to the substrate, and is formed by a high modulus material. An elastic modulus of the high modulus material is E1, and 50 Mpa≤E1≤5 Gpa. The second film layer is formed by a modified energy absorption impact resistance material has viscosity and shear thickening behavior.
