<p>The present invention relates to an optical film comprising a substrate having microstructures and a resin coating disposed on the microstructures of the substrate. The resin coating comprising a plurality of organic particles and a binder. The microstructures comprise a plurality of columnar structures which are equilateral, and the organic particles are tangent to the columnar structures. The height of the organic particles is not less than the height of the columnar structures. The optical film of the present invention enables the organic particles to be uniformly and orderly distributed so that the transmitting light is homogenized and the brightness can be enhanced.</p> |
