Abstract
In various embodiments, the present invention is directed to an interior-light-utilizing display obtained by laminating a reflection structure and a light diffusion film, in which the light diffusion film has an internal structure including a plurality of regions having a relatively high refractive index in a region having a relatively low refractive index in the film. The interior-light-utilizing display provides improved luminance and is capable of stably maintaining constant display characteristics even where the incident angle of the external light changes.
