Abstract
Provided are a window film for a display and a display device including the same, and the window film for a display comprises: a substrate layer; a coating layer formed on one side of the substrate layer; and an adhesive layer formed on the other side of the substrate layer, wherein the coating layer and/or the adhesive layer includes, relative to each layer, a UV absorbent of approximately 3 wt % to approximately 20 wt %, and the window film for a display has a transmittance of approximately 1% or less for a wavelength of 390 nm or less.
Claims13
A window film for displays, comprising:
- a base layer;
- a coating layer directly formed on one surface of the base layer and having a pencil hardness of about 6H or higher;
- and an adhesive layer formed on the other surface of the base layer,
- wherein the base layer is made of an optically transparent material and has a thickness of about 10 μm to about 200 μm,
- wherein at least one of the coating layer and the adhesive layer comprises about 3 wt % to about 20 wt % of a UV absorbent in each layer,
- wherein the coating layer has a thickness of about 20 μm to about 100 μm and is formed of a composition comprising a silicone resin having a crosslinkable functional group, and
- wherein the window film has a transmittance of about 1% or less at a wavelength of 380 nm and a transmittance of about 1% or less at a wavelength of 390 nm.
