Abstract

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.

Description

[0001] Cross reference to related applications [0002] This application claims the benefit of Korean Patent Application No. 10-2007-0076983 filed with the Korean Intellectual Property Office on July 31, 2007, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates to an optical film, and a backlight assembly including the optical film and a liquid crystal display, and more specifically, the present invention relates to a diffusion film achieved through a single film , an optical film with the functions of a prism film and a protective film, and a backlight assembly and a liquid crystal display including the optical film. Background technique [0004] A liquid crystal display is a flat-panel display device that uses the electrical and optical properties of liquid crystals to display images, wherein liquid crystals have properties intermediate between liquid and solid. Liquid crystal displays are thinner and ...
