摘要： A display device includes a display panel including a plurality of sub-pixel areas for respectively outputting light for displaying an image and a light travel-direction changing layer disposed on the display panel for diversifying and spreading travel directions of light emitted from each of the plurality of sub-pixel areas. The light travel-direction changing layer includes a plurality of refractive patterns respectively corresponding to the plurality of sub-pixel areas and arranged in a matrix form, and a light-scattering layer disposed around each of the plurality of refractive patterns and having a refractive index different from a refractive index of each of the plurality of refractive patterns. Due to the light travel-direction changing layer, light from each sub-pixel area is incident into each refractive pattern, is refracted at a boundary between each refractive pattern and the light-scattering layer, and is scattered in the light-scattering layer. Thus, the light emits out of the display device in the diversified and spread travel directions.
