OPTICAL ELEMENT AND BACKLIGHT UNIT AND LIQUID CRYSTAL DISPLAY HAVING THE SAME |
摘要 |
An optical element capable of increasing an angular field while improving luminance by condensing light, and a backlight unit and a liquid crystal display including the same. The optical element includes a light-transmitting base film; a plurality of diffusing cavities or convex diffusing structures formed in one surface of the base film to diffuse light entering the base film; and a light-condensing pattern formed in the surface of the base film where the diffusing cavities or convex diffusing structures are formed so as to condense incident light.
