Abstract
An optical compound sheet for a backlight module includes a base layer formed of a transparent material, a plurality of structured patterns formed on the base layer at a predetermined interval, a light-condensing layer which includes a surface coating including nano-particles distributed on the surface of the structured patterns at the thickness of 0.01 μm to 1 μm, and an anti-scratching layer which is coated under the base layer at the thickness of 0.1 μm to 3 μm by using the UV-curable bond containing nano-particles. While improving the anti-scratching performance by using the surface coating and the anti-scratching layer containing the nano-particles, the wet-out and Moire phenomena are greatly reduced by the finely separate coating of the nano-particles, thereby achieving both the light-condensing function and light-diffusing function.
