Display device
A display device is provided. The display device includes an anti-reflection film. The anti-reflection film includes a base film, a retardation coating layer disposed on a first side of the base film so as to delay a phase of transmitted light, and a polarizer coating layer disposed on a second side of the base film so as to allow a polarization component of the transmitted light in a specific direction to pass through, wherein the retardation coating layer and the polarizer coating layer are formed by applying a liquid crystal on the base film.
1. A display device comprising:
an anti-reflection film, wherein the anti-reflection film includes:
a base film formed of a flexible material selected from a group consisting of an elastomer and polyurethane;
a retardation coating layer disposed on a first side of the base film and configured to delay a phase of transmitted light; and
a polarizer coating layer disposed on a second side of the base film and configured to pass through a component of the transmitted light polarized in a specific direction,
wherein the retardation coating layer and the polarizer coating layer are formed by applying a liquid crystal on the base film,
wherein the base film has an in-plane retardation value (Rin) of 4 nm or less when a wavelength of the transmitted light is greater than 450 nm, and
wherein the base film has a thickness-direction retardation value (Rth) of 10 nm or less.
2. The display device of claim 1 , wherein the polarizer coating layer is disposed on the base film, and the retardation coating layer is disposed beneath the base film.
3. The display device of claim 2 , wherein the anti-reflection film further includes:
an over-coating layer disposed on the polarizer coating layer; and
an insulating coating layer disposed beneath the retardation coating layer.
4. The display device of claim 3 , further comprising:
a touch screen panel, wherein the insulating coating layer is attached to the touch screen panel.
5. The display device of claim 2 , wherein:
the retardation coating layer delays the phase of the transmitted light by a quarter wavelength (A/4),
a first direction of an optical transmission axis of the retardation coating layer and a second direction of an optical transmission axis of the polarizer coating layer form an angle of 45°, and
a third direction of an optical transmission axis of the base film is the same as the second direction of the optical transmission axis of the polarizer coating layer.
