Abstract: A display device includes a display panel, a light source, and an optical component including a light guide film and an optical sheet. The optical sheet is coupled to the light guide film to control a path of a light emitted from the light guide film. The optical sheet includes a base film, main optical patterns, and sub-optical patterns. The main optical patterns are disposed between the base film and the light guide film and coupled to the base film and the light guide film. Each of the main optical patterns includes a side surface inclined with respect to the light guide film. The sub-optical patterns are disposed between the base film and the light guide film, coupled to the base film, and spaced apart from the light guide film. Each of the sub-optical patterns has a side surface inclined with respect to the light guide film.

Abstract: A display device includes a backlight unit and a display panel disposed on the backlight unit. The backlight unit includes a light guide plate including a plurality of charged particles, a light source unit disposed at a side of the light guide plate and providing light to the light guide plate, and a transparent electrode disposed under the light guide plate. Each of the plurality of charged particles includes first and second charged portions which have charge values of which polarities are different from each other. The first charged portion reflects the light received from the light source unit, and the second charged portion absorbs the light received from the light source unit. Positions of the first and second charged portions of each of the plurality of charged particles are controlled based on a voltage applied to the transparent electrode.
