摘要： 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.

摘要： 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.
