Abstract
In a method of manufacturing an optical sheet, a stacked structure may be formed by alternatively and repeatedly stacking at least one transparent layer and at least one light scattering layer. A first cut face may be formed by partially cutting the stacked structure. A second cut face may be formed by partially cutting the stacked structure. The second cut face may be parallel to the first cut face.
