Abstract: An optical film is provided. The optical film includes a base film and a cover film. The base film includes a base member and a plurality of lens patterns disposed on the base member. The plurality of lens patterns protrudes from the base member and extends in a first direction. The cover film is disposed on the base film to cover the base member and the plurality of lens patterns. A refractive index of at least one of the lens patterns is smaller than a refractive index of the cover film. An aspect ratio of the at least one of the lens patterns ranges from 0.8 to 1.6.

Abstract: Provided are a backlight assembly and a display device having the same. A backlight assembly includes a light source unit which emits light, a light guide plate (LGP) including an incident surface upon which light emitted from the light source unit is incident, an opposite surface which faces the incident surface, and an exit surface which connects the incident surface and the opposite surface and from which light incident upon the incident surface exits, a wavelength conversion member which is located on the exit surface and converts a wavelength of light output from the exit surface, and a first reflective member which is located on the opposite surface and reflects light incident upon the opposite surface, wherein the first reflective member includes a plurality of first color patterns which face the opposite surface.
