<p><P>PROBLEM TO BE SOLVED: To provide an optical sheet which is superior in anti-sticking property, includes high total light transmittance, can effectively suppress an interference phenomenon and luminance irregularity and includes high economical efficiency and thin film characteristic, and to provide a backlight unit using the optical sheet. <P>SOLUTION: The optical sheet includes a transparent base film, an optical layer laminated on one side surface of the base film and an anti-sticking layer laminated on the other side surface of the base film, wherein the anti-sticking layer includes fillers and a resin binder, an average thickness of a flat part of the anti-sticking layer is 50 nm to 150 nm and an average particle size of the fillers is 70 nm to 200 nm. As the fillers, small-size fillers of main component and large-size fillers of sub component are included, and the average particle size of the small-size fillers is preferably set to be 50 nm to 150 nm. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
