OPTICAL SHEET AND BACKLIGHT ASSEMBLY AND LIQUID CRYSTAL DISPLAY COMPRISING THE SAME

摘要

Provided are an optical sheet, and a backlight assembly and a liquid crystal display including the optical sheet. The optical sheet includes a transparent base, and plural three-dimensional pattern layers sequentially disposed on one surface of the transparent base. A single optical sheet has a multi-function of photo refractivity, condensing and light diffusion, and requires neither a masking film nor a protective film to thereby be excellent in cost reduction, productivity and workability. Thus, lighter, thinner, simpler and smaller liquid crystal display can be accomplished.
