An optic film has a surface on which a plurality of rib-like micro light guides is formed. Each micro light guide includes a plurality of ridges, which are of different heights and show variation of height. Either a high ridge or a low ridge of the micro light guide is made a continuous left-and-right wavy configuration and/or a continuous up-and-down height-variation configuration. The high ridge has a top that is rounded, whereby by means of the rounded top of the high ridge, the high ridge of the optic film is protected from abrasion and wear or is prevented from causing damage to other parts of an optic device. Thus, protection of the optic film and other parts can be realized.
