摘要： 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.

摘要： Provided is a backlight unit including a printed circuit board, a light-emitting diode package, a diffusion plate, and a reflection sheet. The light-emitting diode package including a light-emitting part configured to generate a first light. The diffusion plate includes a first diffusion pattern provided on a first region corresponding to the light-emitting diode package and a second diffusion pattern provided on a second region to have a transmittance higher than that of the first diffusion pattern. The reflection sheet includes an absorption pigment configured to absorb a fraction of the first light with a specific wavelength and converting the first light to a second light, and the reflection sheet is configured to reflect the second light toward the first diffusion pattern. The backlight unit can have improved color coordinate uniformity.
