<p>The present invention discloses an optical film. An optical film of the present invention comprises micro-shaped optical patterns formed on at least one surface thereof, each optical pattern has a peak and comprises defect-correcting structures formed thereon, and the defect- correcting structure is formed in areas within a height range of 30 or 40% from the peak based on the height of the optical pattern. The defect-correcting structures are one of the groups consisting of micro prominences, depressions, micro scratches, and burrs, and each of the optical patterns has any one sectional shape of a triangular shape, a polygonal shape and an arc shape. Also, the optical patterns are disposed in parallel and spaced from each other at predetermined interval. The optical film according to the present invention further comprises a plurality of micro lens patterns having arc-shaped optical sections formed below the optical patterns. The micro lens patterns have any one of a protruding shape and depressed shape.</p> |
