PURPOSE: An optical film and a manufacturing method thereof are provided to improve a light concentration effect and scratch resistance. CONSTITUTION: The upper side of a base layer(110) is formed into a prism shape(120) in order to concentrate transmitted light. The prism shape is formed on the upper side of the base layer in totality. The prism shape improves brightness by condensing a progressive direction of light. The prism shape condenses or reflects the light. Light condensed by a light concentration pattern is moved to a liquid crystal panel direction. The reflected light is re-reflected through a reflective sheet and is condensed. |
