Abstract
An optical film including a first layer and a second layer disposed on the first layer and attached to the first layer is provided. The first layer has a plurality of micro-structures respectively extending along a first direction and arranged side by side at an interval. The micro-structures protrude toward the second layer. A first pitch exists between each micro-structure and an adjacent micro-structure in a side-by-side arrangement direction. The first pitch is greater than 10 times a wavelength of an incident light. Moreover, a display device including the foregoing optical film is also provided.
