Abstract
An optical film for reducing color shift in an LCD is disposed in front of a liquid crystal panel of the LCD. The optical film includes a background layer, a plurality of engraved lens sections formed in the background layer such that the engraved lens sections are spaced apart from each other, and packed portions, each of the packed portions being disposed inside a respective one of the engraved lens sections. The refractive index of the packed portions is different from that of the background layer. The packed portions are partially packed inside the engraved lens sections. The refractive index of the packed portions is greater than that of the background layer. The background layer and the packed portions are made of transparent polymer resin.
