Abstract: The present disclosure relates to a flexible display device, and according to an aspect of the present disclosure, a flexible display device includes a display panel including a folding area and a non-folding area; a back plate which is disposed below the display panel and supports the display panel; and a bottom plate which is disposed below the back plate and includes a plurality of grooves so as to correspond to the folding area, and a plurality of nano helix structures disposed so as to correspond to the plurality of grooves. Therefore, the flexible display device forms a groove pattern in the bottom plate, and includes a nano helix structure in each of the plurality of grooves, to effectively relieve the folding stress and reduce the visibility of the pattern, finally an appearance quality may be improved.
