Abstract: A display device includes a backlight unit. The backlight unit may include a first light guide plate (LGP) comprising a first optical material and a second optical material. The first LGP is configured to emit light guided through the second optical material toward a display panel using the first optical material. The backlight unit may include a second LGP disposed between the first LGP and the display panel. The second LGP is configured to emit light toward the display panel using a diffuser plate provided in a lower portion of the second LGP. The backlight unit may include light sources configured to provide, under control of a controller, light to the first LGP if a three-dimensional (3D) image is displayed on the display panel, and to provide light to the second LGP if a two-dimensional (2D) image is displayed on the display panel.
