A display device having a display panel including first and second folding areas, a first non-folding area between the first and second folding areas, and a second non-folding area. A panel support is disposed on a lower side of the display panel and includes a first lattice pattern overlapping the first folding area, a second lattice pattern overlapping the second folding area, a first flat plate overlapping the first non-folding area, and a second flat plate overlapping the second non-folding area. An adhesive member is interposed between the display panel and the panel support and includes a first adhesive member disposed directly on the first flat plate and a second adhesive member disposed directly on the second flat plate. An adhesive force between the first adhesive member and the first flat plate is greater than an adhesive force between the second adhesive member and the second flat plate.

Display device

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 flexible display device including a display panel configured to display an image, a touch screen panel on the display panel, and a window substrate covering the touch screen panel. The window substrate includes: a flexible base layer including a first surface facing an outside and a second surface facing the display panel in an opposite direction to the first surface; a first coating layer having hardness higher than that of the base layer and having a plurality of first coating tiles arranged on the first surface of the base layer thereof, at a first gap from each other; and a second coating layer having hardness higher than that of the base layer and having a plurality of second coating tiles arranged on a layer different from the first surface of the base layer thereof, at a second gap from each other.

Flexible window substrate and flexible display device having the same

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.

There is provided a flexible display device including a display panel for displaying an image, and a window substrate covering the touch screen panel, the widow substrate including a flexible base layer including an externally facing first surface, and a second surface opposite the first surface and facing the display panel, a hard coating layer having a hardness that is larger than that of the base layer, and including a plurality of coating tiles on the first surface of the base layer that are spaced to have a gap between adjacent ones of the coating tiles, and a self-healing coating layer including a self-healing material and covering the hard coating layer on the base layer.

A display device according to one or more embodiments of the present invention includes: a flexible display panel that is configured to be widened or narrowed, the flexible display panel including a display part configured to display an image at a first surface of the flexible display panel, and a bending part configured to be folded in a direction away from the display part; and a driving unit including one or more rollers in close proximity to the bending part, and configured to rotate to widen or narrow the flexible display panel.

A stretchable display device, including a stretchable display panel to display images; and a window on a touch sensing layer, the window including a soft part and a plurality of hard parts attached on a surface of the soft part, the hard parts including an attachment portion attached to the soft part and a non-attachment portion not attached to the soft part.

Stretchable display device

A window panel includes a plurality of unit patterns arranged along a first direction, each of the plurality of unit patterns having a base surface portion, a plurality of inclined portions, the plurality of inclined portions being inclined upwardly from the base surface portion, and a top portion disposed at a top of the inclined portions, wherein a lower edge of a first inclined portion of each unit pattern of the plurality of unit patterns adjoins a lower edge of a second inclined portion of a neighboring unit pattern.

Window panel and display device including the same

A flexible display device includes a flexible display panel, a touch sensing layer on the flexible display panel, and a window on the touch sensing layer. The window may include an elastic portion and a plurality of rigid portions at a surface of the elastic portion and separated from each other. The elastic portion may be made of a soft material having elastic characteristics, and the rigid portion may be made of a hard material. The rigid portion may have a checkered pattern or a striped pattern at the surface of the elastic portion. The flexible display device may also include a barrier film at a surface of the flexible display panel. The barrier film may protect the flexible display panel and the touch sensing layer from external impacts.
