Abstract
A display device is disclosed. The display panel may comprise a display panel including a pixel area and a light refraction element disposed on the display panel. The light refraction element may have a first face facing the display panel and a second face disposed at an opposite side of the first face. The light refraction element may comprise a light refraction pattern disposed at the first face and having a first slanting face and a second slanting face, and the light refraction pattern can refract light emerging from the display panel.
