A window includes a base layer, and an inorganic film disposed directly on at least one selected from an upper surface and a lower surface of the base layer, where the inorganic film includes at least one selected from silicon oxy carbide, silicon oxy carbonitride, and silicon oxide.

Window, and display device including the same

A display device includes a display panel that may be folded with reference to at least one folding axis, a polarization layer disposed on the display panel, an adhesive layer disposed on the polarization layer, and a window disposed on the adhesive layer, and having one surface facing the adhesive layer. A 180 degree (°) peel adhesion of the adhesive layer to the one surface of the window may be about 493 gram-force per inch (gf/inch) to about 817 gf/inch under the conditions of a temperature of about 60 degrees Celsius (° C.) and a relative humidity of about 93 percent (%). Accordingly, the display device including the adhesive layer may exhibit good durability, and maintain the reliability thereof.

Display device including foldable display panel

A display device includes a display panel, a panel protective film disposed below the display panel, and a first adhesive layer disposed between the display panel and the panel protective film, where a test speed of a tensile test of the panel protective film is about 5 millimeters per minute (mm/min), Young's modulus of the panel protective film is measured in a range of strain in which strain of the panel protective film is about 0.05 percent (%) to about 0.5%, and the panel protective film has the Young's modulus of about 4324 megapascals (MPa) to about 4792 MPa at about 25 degrees Celsius.

Display device and carrier film

A protective window includes a flexible base film and a hard coating layer disposed on the flexible base film. The hard coating layer includes a silicone leveling agent and an inorganic antistatic agent. The coating layer includes an upper area and a lower area disposed between the upper area and the flexible base film, and a density of the inorganic antistatic agent in the lower area is greater than a density of the inorganic antistatic agent in the upper area.

Protective window including a hard coating layer and flexible display device including the same

A display device includes: a display panel; a window disposed on the display panel; a window protection layer disposed on the window; and a first adhesive layer disposed between the window and the window protection layer; wherein the first adhesive layer has a creep value of about 38.1876% to about 40.4371% at a temperature of about 25&#xb0; C. when a stress of about 2,000 Pa is applied to the first adhesive layer for about 10 minutes, the first adhesive layer has a storage modulus of about 0.0317 MPa to about 0.0348 MPa, a loss modulus of about 0.0108 MPa to about 0.0120 MPa, and a tan delta value of about 0.3354 to about 0.3480 at the temperature of about 25&#xb0; C. when a frequency of about 1 Hz and an axial force of about 1.0 N are applied and the first adhesive layer maintains a strain of about 1%, and the tan delta value is defined by dividing the loss modulus by the storage modulus.

Display device

A display device includes a display module and a window member disposed on the display module, where the window member includes a base layer and a hard coating layer disposed on the base layer. A moisture absorption ratio of the window member is about 2.2% or greater under a first condition including a first temperature and a first humidity. The first temperature is about 60&#xb0; C. or greater, and the first humidity is about 70% or greater.
