Abstract: A flexible display apparatus includes a bending area and a non-bending area. The flexible display apparatus further includes a display panel and a polarizing structure disposed on the display panel. The polarizing structure includes a λ/4 phase retardation layer, a linear polarizer disposed on the λ/4 phase retardation layer, and a first adhesive structure disposed between the λ/4 phase retardation layer and the linear polarizer. The linear polarizer includes a stretched polymer film. The first adhesive structure is an adhesive layer with a glass transition temperature that is greater than or equal to 40° C. and less than or equal to 150° C. Accordingly, deformation of the λ/4 phase retardation layer may be prevented or reduced when the flexible display apparatus is folded or bent, thereby improving display quality.

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.

Abstract: A display device includes a display panel including a folding area and a non-folding area disposed adjacent to the folding area, and a first support plate disposed on a lower portion of the display panel. The non-folding area includes a first display area and a second display area disposed adjacent to the first display area and having a higher light transmittance than the first display area. A first hole overlapping the second display area is defined in the first support plate, and a size of the first hole is larger than a size of the second display area in a plan view.
