Abstract
Embodiments of the present disclosure relate to a light conversion film, a backlight unit and a display device, and according to the embodiments, white light can be produced by a simplified configuration and be uniformly provided to a panel by disposing, over areas corresponding to light sources, patterns changing traveling paths of light emitted from a light source and patterns converting wavelengths of light. Further, by allowing a base film to provide a function of guiding light by disposing, over a light source, the base film on which a light path change pattern and a color conversion pattern are disposed to be adjacent to the light source, it is possible to minimize a thickness of the backlight unit and enhance image quality presented by illumination of the backlight unit.
