A window member includes a window including a first flat part, a first pattern part disposed on a side of the first flat part and having a groove pattern, and a second flat part disposed on an opposite side of the first flat part, the first pattern part being disposed between the first flat part and the second flat part; and a first light-blocking member disposed on a surface of the first flat part and not overlapping the first pattern part or the second flat part in a plan view. The first light-blocking member includes a 1-1-th light-blocking member, a 1-2-th light-blocking member, and a 1-3-th light-blocking member facing the 1-1-th light-blocking member. The 1-1-th light-blocking member, the 1-2-th light-blocking member, and the 1-3-th light-blocking member define a first accommodation space. The 1-3-th light-blocking member is spaced apart from the 1-1-th light-blocking member to define a first open area.

A display device is disclosed. The display device includes a flexible display panel, a module cover positioned behind the flexible display panel, a panel roller coupled to a lower end of the flexible display panel, a subsidiary roller spaced apart from the panel roller and positioned adjacent to a front side of the flexible display panel, a protective sheet in contact with a front side of the flexible display panel when the protective sheet is wound around the panel roller together with the flexible display panel and the module cover, a filler coupled to the subsidiary roller, wherein a portion of the filler is configured to be in contact with the front side of the flexible display panel and a distance between a rotational axis of the panel roller and a rotational axis of the subsidiary roller is fixed.

Implementations for composite display cover are described and provide improved protection and durability to device displays as compared with conventional display protection technologies. The described composite display cover, for instance, utilizes an ultra-thin glass layer with a polymer film applied directly to the glass layer and a hard coat applied to the polymer film. The polymer film, for instance, is applied to the glass layer without an adhesive. Further, the composite display cover can be attached to a display, such as via an adhesive layer that adheres the glass layer to a surface of the display.

A method of manufacturing a cover window includes: cutting mother glass into panel glass; chamfering the panel glass; etching an entire surface of the panel glass with a first etching solution including a fluorine-based compound; etching the entire surface of the panel glass with a second etching solution different from the first etching solution; and cleaning the panel glass with a basic cleaning solution.

A method for producing a composite pane, includes arranging a functional element in a recess of a thermoplastic frame film, arranging the thermoplastic frame film along with the functional element between a first glass pane and a second glass pane to form a layer stack, and subsequent joining of the layer stack by lamination to form a composite pane. The thermoplastic frame film and the functional element have a different thickness and the different thickness is at least partially compensated by at least one thermoplastic compensating film, whose thickness is less than twice as large as the difference between the thicknesses of the thermoplastic frame film and the functional element such that the maximum offset in the layer stack is less than the difference between the thicknesses of the thermoplastic frame film and the functional element.
