Abstract

A light deflection film and a display device using the same are provided. The display device includes a display panel and a light deflection film. The light deflection film is disposed on the display panel and includes a first layer, a second layer and a light deflection structure formed at an interface between the first layer and the second layer. The first layer has a first refractive index. The second layer is formed on the first layer and has a second refractive index. The first layer of the light deflection film is located between the second layer and the display panel, and the first refractive index is larger than the second refractive index.
