Abstract: A display device includes a display module, a light guide plate, a light source disposed at a side of the light guide plate in a first direction, the light source including light source units arranged in a second direction, and a condensing sheet including reverse prisms. The display module includes first and second polarizing plates facing each other, a display unit including a liquid crystal layer, and a light-conversion structure. In a plan view, the light source units include first and second light source units, which are parallel to third and fourth directions, respectively. The third and fourth directions are at angles of +45° and −45° to the first direction. Each reverse prism includes a base surface that is parallel to the plane and includes two sides parallel to the third and fourth directions, respectively.

Abstract: A backlight unit includes: a light guide member including an light incident surface which receives light, a light emitting surface bent from the light incident surface, and a rear surface bent from the light incident surface and parallel to the light emitting surface; a light source which provides light to the light incident surface; and a refractive index control member disposed on the rear surface and divided into a plurality of areas on a plane parallel to the light emitting surface, where an electric field is generated for each area. Each of the areas is in a first state to have a first refractive index or in a second state to have a second refractive index, which is different from the first state, based on the electric field generated therein.
