Abstract: A display device includes a display module on which a first non-folding area, a folding area, and a second non-folding area are sequentially defined in a first direction and which is deformable between a first state that is an unfolded sate and a second state that is a folded state and a sheet member including a first support portion overlapping the first non-folding area, a second support portion overlapping the second non-folding area, and a restoration portion overlapping the folding area, which are disposed below the display module. When the display module is in the first state, the restoration portion has an elastic force.

Abstract: A display device includes a display panel which displays an image, an anti-reflection film disposed on a display surface of the display panel, and a plurality of retardation films disposed on the anti-reflection film. Each of the plurality of retardation films has an in-plane retardation of about 1000 nanometers to about 7000 nanometers.

Abstract: A method for manufacturing a display module that is variable from a first state, which is unfolded, to a second state, which is folded with respect to a folding axis, may include folding the display module into a third state that is different from the second state, and performing a first heat treatment on the display module in the third state at a first temperature.
