Abstract: A display device includes a display module including a folding area and a non-folding area, an impact absorbing layer disposed under the display module and including a bending area and a non-bending area, and a support layer disposed under the impact absorbing layer and including a first sub-support layer overlapping a first non-folding area and a second sub-support layer spaced apart from the first sub-support layer and overlapping a second non-folding area. The first sub-support layer includes a first opening group formed through the first sub-support layer and spaced apart from a first cross-section surface adjacent to the second sub-support layer in a direction opposite to a second direction, and the second sub-support layer includes a second opening group formed through the second sub-support layer and spaced apart from a second cross-section surface adjacent to the first sub-support layer in the second direction.

Abstract: Provided is a display device including a display module, an anti-reflection layer, and a bending protection layer. The display module includes a first area, a second area, and a bending area disposed between the first area and the second area and having a predetermined curvature radius. The bending protection layer includes a first portion overlapping at least the first area and a second portion overlapping at least the bending area. The first portion has a maximum thickness in a range from about 40 μm to about 85 μm, a maximum inclined angle in a range from about 10° to 30°, and an elastic modulus in a range from about 50 MPa to about 300 MPa.

Abstract: A display device includes a display module including in order along a first direction: a first non-folding area, a folding area at which the display device is foldable, and a second non-folding area, a first supporter on which the first non-folding area is disposed, a second supporter on which the second non-folding area is disposed, a first adhesive between the first non-folding area and the first supporter, and a second adhesive between the second non-folding area and the second supporter. Within the folding area, a first distance along the first direction between, the first adhesive and the second adhesive, is both: greater than a second distance along the first direction, between the first supporter and the second supporter, and smaller than a length of the folding area, along the first direction.
