An optical film for display is provided. The optical film for display is an optical film for display, which is arranged on an image source unit for providing an image source and displays an image by refracting the image source provided by the image source unit. The optical film for display comprises a first surface facing the image source unit, a second surface on the opposite surface of the first surface, and a light refraction pattern disposed on the first surface and comprising at least two inclined surfaces, and the optical film for display meets the condition of the following formula: sin-1(1/n) ＜ α. In the formula, the n represents a refraction rate of the optical film for display, and the α represents any angle of inclination among the angles of inclination at which the inclined surfaces are tilted with respect to the image source unit. |
