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 9):
A backlight unit for a liquid crystal display device comprising:\n a light guide film or a light guide plate for guiding toward a front face side thereof rays of light having entered from an end face side thereof, one or more LED light sources that are disposed on the end face side of the light guide film or the light guide plate and are for emitting rays of light to an end face of the light guide film or the light guide plate; and the optical sheet according to  claim 1  overlaid on the front face side of the light guide film or the light guide plate.
