Abstract: A display device includes a display panel, a light guide plate disposed under the display panel, a light source disposed adjacent to one side surface of the light guide plate that generates a first light, a first refractive layer disposed between the light source and the one side surface of the light guide plate that has a refractive index greater than a refractive index of the light guide plate, and a second refractive layer disposed between the display panel and the light guide plate that has a refractive index less than the refractive index of the light guide plate. The first refractive layer includes a convex portion that protrudes into the one side surface of the light guide plate.
