OPTICAL FILM, LIGHT SOURCE ASSEMBLY INCLUDING THE SAME, AND METHOD OF FABRICATING MOLD FOR OPTICAL FILM

摘要

Provided are an optical sheet, a backlight assembly including the same, and a method for manufacturing an optical sheet molding mold. The optical sheet comprises: a first base material; a first light modulation layer formed on an upper surface of the first base material; a second base material arranged on an upper portion of the first base material; and a coupling layer formed on a lower surface of the second base material and coupled to the first light modulation layer by enabling the first light modulation layer to partially touch or penetrate the coupling layer. The coupling layer includes a reference surface and embossed patterns which protrude from the reference surface. The embossed patterns are arranged with a period. A surface of the coupling layer, which faces the first light modulation layer, comprises fine uneven parts.
