Abstract: A display device includes a display panel foldable with respect to a folding axis substantially parallel to a first direction and a support plate disposed under the display panel and including a folding plate foldable with respect to the folding axis. The folding plate includes at least one first support layer and at least one second support layer. The folding plate has a first elastic modulus corresponding to a bending strength with respect to a second direction intersecting the first direction and a second elastic modulus corresponding to a bending strength with respect to the first direction. The first elastic modulus is smaller than the second elastic modulus.

Abstract: A display apparatus includes: a flexible first layer including a bending area; an adhesive layer on an upper surface of the flexible first layer; and a second layer attached to the flexible first layer by the adhesive layer. A direction of internal stress at a first portion of the flexible first layer is different from a direction of internal stress at a second portion of the flexible first layer, when the flexible first layer is in a flat state.

Abstract: A display device includes a display module, a protection film, and a complementary film. The display module is foldable with respect to a first bending axis and a second bending axis spaced apart from the first bending axis. The protection film is below the display module, overlaps the first bending axis and the second bending axis, and includes a polymer material. The complementary film is below the protection film, overlaps only the second bending axis of the first and second bending axes, and includes a metal.
