Abstract
The present invention provides a window film, a manufacturing method thereof, and a display device including the same. The window film comprises: a basic material layer; a window coating layer formed on one surface of the basic material layer; and a back coating layer formed on the other surface of the basic material layer, wherein the window film has a relation of formula 1.
Claims21
A window film comprising:
- a base layer;
- a window coating layer directly formed on one surface of the base layer;
- and a back coating layer directly formed on the other surface of the base layer,
- wherein the window film satisfies Equation 1:
- A1<A2<A3 <Equation 1>
- (where A1 is an index of refraction of the back coating layer, A2 is an index of refraction of the window coating layer, and A3 is an index of refraction of the base layer).
3 more elements
A method of preparing window films, comprising:
- forming a back coating layer on one surface of a base layer using a back coating layer composition;
- and
- forming a window coating layer on the other surface of the base layer using a window coating layer composition,
- wherein the back coating layer composition comprises:
- inorganic hollow particles;
- at least one of a fluorine-containing monomer or an oligomer thereof;
- at least one of a fluorine-free monomer or an oligomer thereof;
- an initiator;
- a dye;
- and a solvent.
