OPTICAL FILM, METHOD OF MANUFACTURING THE SAME, AND DISPLAY APPARATUS HAVING THE SAME
First Claim
1. An optical film comprising:
- a base film;
a plurality of thin film patterns disposed on the base film to be spaced apart from each other, the thin film patterns having a first property corresponding to one of a hydrophilic property and a hydrophobic property; and
a plurality of cholesteric liquid crystals having the first property and respectively disposed on the thin film patterns so as to transmit one of a right-circularly polarized light and a left-circularly polarized light and reflect the other one of the right-circularly polarized light and the left-circularly polarized light.

Abstract
An optical film includes a base film, thin film patterns, and cholesteric liquid crystals. The thin film patterns are disposed on the base film to be spaced apart from each other and have a first property corresponding to one of a hydrophilic property and a hydrophobic property. The cholesteric liquid crystals have the first property and are disposed on the thin film patterns to transmit one of a right-circularly polarized light and a left-circularly polarized light and reflect the other one of the right-circularly polarized light and the left-circularly polarized light. A display apparatus includes a light source unit emitting a light, a display panel receiving the light and controlling a transmittance of the light to display an image, and an optical film disposed between the light source unit and the display panel.

13. A display apparatus comprising:
-
a light source unit emitting a light; a display panel receiving the light and controlling a transmittance of the light to display an image; and an optical film disposed between the light source unit and the display panel, wherein the optical film comprises; a base film; a plurality of thin film patterns disposed on the base film to be spaced apart from each other, the thin film patterns having a first property selected from a hydrophilic property and a hydrophobic property; and a plurality of cholesteric liquid crystals having the first property and respectively disposed on the thin film patterns to transmit one of a right-circularly polarized light and a left-circularly polarized light and reflect the other one of the right-circularly polarized light and the left-circularly polarized light. - View Dependent Claims (14, 15, 16)

17. A method of manufacturing an optical film, comprising:
-
forming a plurality of thin film patterns on a base film to be spaced apart from each other, the thin film patterns having a first property corresponding to one of a hydrophilic property and a hydrophobic property; forming cholesteric liquid crystals on the thin film patterns, respectively, the cholesteric liquid crystals having a reactive mesogen and representing a blue color; and non-uniformly irradiating a light onto the cholesteric liquid crystals to change a part of the cholesteric liquid crystals to a red cholesteric liquid crystal representing a red color or a green cholesteric liquid crystal representing a green color. - View Dependent Claims (18, 19, 20)
