Abstract: The present invention relates to a highly-reliable reflective sheet for an LCD backlight unit and a manufacturing method thereof. In the highly-reliable reflective sheet for an LCD backlight unit, soft spherical particles having a size of 1 to 100 um are applied and coated on one surface of a reflective sheet or a polyethylene terephthalate (PET) film, where pores are formed inside a base material, to give a slip feature, and an adhesive is applied for lamination on the other surface of the reflective sheet or the PET film to increase stiffness and improve reliability. The highly-reliable reflective sheet for an LCD backlight unit having the structure described above, given in the present invention, resolves a surface crack problem by granting a slip feature by coating one surface; increases stiffness of the base material by laminating the reflective sheet or the PET film on the other surface using an adhesive to suppress crumpling and creasing of a sheet and improve reliability. As a result, by improving the crack feature of the surface in contact with a light guide plate while having a high-power and slim backlight structure, the present invention is able to prevent surface damage due to vibrations during transportation and movement and remove crumpling and creasing on the reflective sheet due to the high power of an LED light source, thereby resolving the existing problems.

The lightly peelable releasing film and a hardly peelable releasing film are releasing films having 2-6 times of peeling force difference when peeled at a high speed of 5-30 m/min with an angle of 180 degrees after cutting the adhesive film to a width of 1-2 inches. According to the releasing film for an adhesive film of the present invention and a method of preparing the same, the peeling force difference between the lightly peelable film and the hardly peelable film is controlled to a certain value, and the separating phenomenon of the adhesive during the peeling of the film and the transferring phenomenon to the film may be improved. Through controlling the coating weight of the releasing film, the zippy sound may be improved. In addition, the quality of a double adhesive film may be expected to increase through the releasing film manufactured by the present invention.

Abstract: The present invention relates to a light diffusion sheet for a thin backlight unit having a shielding function capable of preventing hot spots on an LCD backlight unit using LED lamps by regularly diffusing or shielding light from the LED lamps by coating fine particles with a thin film and a manufacturing method thereof. The light diffusion sheet for a thin backlight unit given in the present invention includes: a transparent polyester base film; and a light diffusion layer formed on at least one surface of the film. The light diffusion layer is formed by applying binder resin and a mixture of particles having different diameters and making the particles form a single layer in the binder resin. For the light diffusion sheet for a thin backlight unit described above, binder resin and a mixture of particles having different diameters are applied on the surface of the base film to form a single layer of particles having different diameters. As a result, since the thickness of coating is reduced by 5-7μm compared to the existing light diffusion sheet, the present invention is able to enhance brightness and shielding performance, thereby resolving the problem of the existing light diffusion sheet that the coating layer is too thick to be used for a thin backlight unit.
