Abstract: A flexible display device includes a bending area including a display panel, an optical member, a polarization member, and a window member, and a non-bending area. A bending part of the optical member includes a plurality of optical patterns corresponding to the bending area, and the plurality of optical patterns are provided to have different widths at a face adjacent to the display panel and a face adjacent to the polarization member. Light leakage phenomenon and color shift phenomenon induced by the modification of the optical member in the bending area during bending of the display device may be improved.
