An exemplary embodiment provides a cover window for a display device, including: a first film; a second film disposed on the first film; and an adhesive layer disposed between the first film and the second film, wherein the adhesive layer includes an elastic polymer, and wherein a ratio of a thickness of the second film to a thickness of the first film is in a range of 0.2 to 5.

Cover window for display device and display device including the same

A cover window for a display device includes: a first film; a second film on the first film; and an adhesive layer between the first film and the second film. The adhesive layer has a lap shear modulus in a range of 20 kPa to 50 kPa.

A cover window includes: a base film disposed on a display panel of a display device which displays an image with light; and porous nanoparticles embedded in the base film at a side of the base film opposite to that at which the display panel is disposed.

The present disclosure relates to a window for a flexible display device, including: a first film including a transparent base film and a plurality of holes passing through the transparent base film; a second film overlapping the first film; a buffer layer between the first film and the second film to attach a first side of the first film and a first side of the second film; and a hard coated layer on a second side of the second film.

Window for flexible display device and flexible display device having the same

A foldable display device includes: a display panel having a folded portion bendable along a fold line; and a cover window disposed on the display panel, wherein the cover window includes: at least a soft pattern disposed on the folded portion of the display panel; and a hard coating layer disposed on the display panel having the soft pattern formed thereon, and the soft pattern has a triangular cross section.

Foldable display device

A cover window for a display device includes a first film; a second film on the first film; an adhesive layer between the first film and the second film; a coating layer on the second film; and an inner anti-reflective layer between the first film and the coating layer.

A flexible window and flexible display are disclosed. In one aspect, the flexible window includes a first film having a first Young's modulus, a second film positioned over the first film and having a second Young's modulus that is greater than the first Young's modulus, and a first adhesive layer interposed between the first film and the second film.

Flexible window and flexible display

A flexible display device is disclosed. In one aspect, the display device includes a display substrate and a display element layer formed over the display substrate and including a matrix of pixels. The display device also includes a thin film encapsulation layer formed over the display substrate and the display element layer so as to protect the display substrate and the display element layer. The display device further includes a window layer formed over the thin film encapsulation layer and a hard coating layer formed over the window layer and having greater hardness than the window layer. The hard coating layer comprises an elastic layer including a plurality of fillers.

Flexible display device

Disclosed are an optical film and a preparation method thereof. The optical film comprises a base layer, a plurality of polymer particles disposed in the base layer, and voids formed in the base layer and enclosing the respective polymer particles, wherein the polymer particles comprise a crosslinked polymer. The optical film has uniform voids, enhanced processing and dimensional stabilities, as well as improved optical properties such as whiteness, hiding power, reflectance and the like. Thus, the optical film can be useful for a reflector sheet for a BLU of an LCD device, and the like.

Optical film and preparation method thereof

A white porous polyester film of the present invention comprising a polyester-based monopolymer/copolymer blend, a crystalline polymer resin which is not miscible with a polyester and has a heat deformation temperature of 90&#xb0; C. or higher, inorganic particles, a whitening agent, and a stabilizing agent has improved optical properties, and thus is useful as a film for use in printing, labeling, electronics, and display applications.
