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.
