Abstract: A flexible display device that may fold so that a neutral surface has a radius of curvature is provided. The flexible display device includes a plurality of panel layers that are sequentially stacked on one another and comprise a display panel layer configured to display an image and a transparent protective panel layer; and adhesive layers that sequentially adhere the plurality of panel layers to one another. An elastic modulus and a thickness of each of the adhesive layers and the plurality of panel layers are determined so that a neutral surface is located on a layer other than the display panel layer.
