<p>An optical film comprises a high refractive index pattern layer having a first surface and a second surface facing each other, forming a pattern with multiple engraved grooves including curved surface and having the depth larger than the width formed on the first surface, wherein the multiple grooves are two-dimensionally arranged in the first direction and the second direction, a first distance between grooves adjacent in the first direction and a second distance between the grooves adjacent in the second direction are different, and made of a material having refractive index more than one; and a lower refractive index pattern layer including multiple filling part filling multiple grooves, and made of a material having refractive index lower than the refractive index of the high refractive index pattern layer.</p> |
