Abstract
The present invention relates to an optical film comprising a substrate on which an array of structures is formed, wherein a material having a different refractive index, absorbancy or reflectivity from that of a surface of the structures is partially coated on the surface of the structures, and a manufacturing method thereof. Specifically, the optical film according to one embodiment of the present invention may have a different transparency depending on the direction or can transmit light asymmetrically. Further, the optical film may be applicable to image devices, which need to change brightness or images depending on the angle of view or to display three-dimensional images.
