Abstract: A window for a display device includes: a film having flexibility; and at least one coating layer disposed on the film. As tensile stress acting on the film increases, the film is elastically deformed in a first range of strains of the film and plastically deformed in a second range of strains of the film greater than the first range, the first and second ranges being defined by a relationship between the tensile stress and a strain of the film in accordance with the tensile stress. The film has a yield strain in a third range from about 1.9% to about 2.25%, and the yield strain is defined as the strain of the film when a yield stress of the relationship in the first range is applied to the film.

Abstract: A display device includes a display module which is foldable and includes a first non-folding area, a folding area and a second non-folding area, in order, a first plate corresponding to the first non-folding area, a second plate corresponding to the second non-folding area and spaced apart from the first plate, and a cover film facing the display module with both the first plate and the second plate therebetween. The cover film includes a first film corresponding to each of the first non-folding area, the folding area and the second non-folding area, the first film attached to each of the first and second plates, and at the folding area, a second film attached to the first film. The display module which is folded disposes the second film between the first film and the first plate and between the first film and the second plate.

Abstract: A flexible display window includes a flexible base layer including a flexible resin, a first silica nano particle coating layer including full-type silica nano particles, where the first silica nano particle coating layer is disposed on the flexible base layer, a flexible hard coating layer including a flexible hard coating resin, where the flexible hard coating layer is disposed on the first silica nano particle coating layer, and a second silica nano particle coating layer including hollow-type silica nano particles, where the second silica nano particle coating layer is disposed on the flexible hard coating layer. Thus, the flexible display window can enhance impact-resistance of a flexible display while reducing reflectivity of the flexible display.
