COMPLEX OPTICAL SHEET, LIQUID CRYSTAL DISPLAY USING THE SAME AND METHOD OF MANUFACTURING THE SAME

摘要

A complex optical sheet used in a liquid crystal display device and a manufacturing method thereof are disclosed. The liquid crystal display device comprises: a liquid crystal panel; a surface light emitting module; a base layer arranged between the liquid crystal panel and the surface light emitting module; a diffusion pattern layer formed on a side of the surface light emitting module and configured to diffuse light incident from the surface light emitting module; a prism pattern layer formed on a side of the liquid crystal panel of the base layer and including a plurality of first unit prisms; and a prism film bonded onto the prism pattern layer and including a plurality of second unit prisms. Therefore, the liquid crystal display device can improve scattering features without lowering brightness.
