Abstract: 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.
