A OPTICAL FILM HAVING ROUND-HEXAGONAL PATTERN AND BACKLIGHT ASSEMBLY USING THE SAME

摘要

PURPOSE: An optical film having a smoothing hexagonal pattern and a backlight assembly using the same are provided to improve shielding properties by increasing a light scattering effect and minimizing moire generated in a circular or polygonal pattern. CONSTITUTION: A base layer(101) transmits light from outside. A pattern layer includes a smoothing hexagonal pattern(110,111,112). The smoothing hexagonal pattern is formed on one side of the base layer. The smoothing hexagonal pattern forms a rounded edge by reducing the distance of an inscribed circle by 2/5 to 2/3 in the inscribed circular arc direction.
