1. A surface finishing method, comprising steps of:
providing a resin material, adding a plurality of spherical diffusion particles into the resin material to form an anti-glare material, wherein each of the plurality of diffusion particles has a same density, and the density of the diffusion particles is less than a density of the resin material;
coating the anti-glare material onto a surface of a substrate, wherein a thickness of the resin material in the anti-glare material coated on the surface of the substrate is greater than a particle size of the diffusion particles; and
performing a curing process of the anti-glare material to cure the resin material to form a resin layer, wherein the diffusion particles is evenly dispersed in the resin layer, and a part of a volume of the diffusion particles is exposed on a surface of the resin layer, thereby giving the substrate a predetermined surface haze.
