Abstract
A display device includes a display panel and a backlight unit. The display panel receives a light to display an image and has a first radius of curvature. The backlight unit is disposed under the display panel to provide the light to the display panel and has a second radius of curvature. The backlight unit includes a plurality of light sources and a plurality of scattering units. The light sources emit the light and the scattering units scatter at least a portion of the light.
Claims20
A display device comprising:
- a display panel having a first radius of curvature, responding to light by displaying variable visual images;
- and
- a backlight unit disposed providing the light to the display panel, the backlight unit having a second radius of curvature,
