Abstract: A display device includes a display panel and a backlight unit which provides light to the display panel. The backlight unit includes a light source which emits the light, a light guide plate which guides the light emitted from the light source toward the display panel, and a prism plate. The prism plate includes a base film disposed on the light guide plate and a plurality of prisms disposed on the base film. Each of the prisms has an isosceles trapezoidal section, two base angles of which are obtuse angles, when viewed from a cross-sectional view in a width direction.

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.
