Abstract:
An optical film for reducing color shift and an LCD having the same. The optical film is disposed in front of a display panel of the LCD. The optical film includes a background layer and a plurality of engraved or embossed lens sections formed in the background layer such that they are spaced apart from each other. When light having different colors depending on a viewing angle and a grayscale level is emitted, a portion of the light incident onto the lens sections is diffused, and is thus mixed with another portion of the light passing between adjacent lens sections. The cross-section of the lens sections includes first, second and third sides. The first and second sides face each other and are connected by the third side. The average curvature of the third side is smaller than that of the first side and than that of the second side.
