Abstract
The present disclosure provides a display device and a backlight source. The display device includes a liquid crystal panel and a backlight source. The liquid crystal panel includes a color filter substrate, an array substrate arranged opposite to the color filter substrate, and a blue phase liquid crystal layer arranged between the color filter substrate and the array substrate. A first driving electrode is arranged at a side of the color filter substrate facing the array substrate, and a second driving electrode is arranged at a side of the array substrate facing the color filter substrate. The backlight source includes: a light guide plate; and a composite layer arranged at a light-exiting surface of the light guide plate and including a plurality of dielectric layers whose refractive indices decrease gradually in a direction away from the light-exiting surface of the light guide plate.
