Abstract: A display device includes a display panel including a first non-folding area, a folding area, and a second non-folding area and a support plate that is disposed under the display panel and that defines a plurality of openings overlapping the folding area and arranged in a first direction and a second direction intersecting the first direction. The support plate includes a first branch disposed between openings adjacent to each other in the second direction among the plurality of openings and a second branch disposed between openings adjacent to each other in the first direction among the plurality of openings. A first width of the first branch in the second direction is smaller than a second width of each of the openings in the second direction.

Abstract: A display device which includes a display panel and a protection member above the display panel. The protection member may include an adhesive layer above the display panel, a first protection layer above the adhesive layer, and a second protection layer between the first protection layer and the adhesive layer. The first protection layer may have a first thickness and a first modulus, and the second protection layer may have a second thickness less than the first thickness and a second modulus less than the first modulus. The minimum value of the second thickness may be 20 μm, and the maximum value of the second thickness may satisfy Equation (1) below. The display device, which includes the protection member including the second protection layer satisfying Equation (1), may improve impact resistance and maintain reliability.

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.
