Abstract:
An optical sheet for a backlight unit for guiding toward a front face side rays of light emitted by an LED light source. The optical sheet includes one or more resin layers. Ultrafine grooves oriented in specific directions are provided on a front face side or a back face side of at least one resin layer of the one or more resin layers. An average number of the ultrafine grooves per unit length in a direction perpendicular to an average orientation of the ultrafine grooves is preferably no less than 10/mm and no greater than 10,000/mm. A face of the at least one resin layer provided with the ultrafine grooves preferably has an arithmetic average roughness (Ra) in a direction perpendicular to an orientation of the ultrafine grooves being no less than 0.01 μm and no greater than 5 μm. Ultrafine grooves preferably constitute a diffraction grating.

Claim (Index 7):
The optical sheet for a backlight unit according to  claim 1 , further comprising a functional layer comprising projections and recesses provided on a front face thereof.
