Abstract: A surface finishing method, an anti-glare coating, and a display device having same are provided. The surface finishing method includes adding diffusion particles which have a density less than that of a resin material, and controlling the thickness of the resin material in an anti-glare material coated on a surface of a substrate to be greater than the particle size of the diffusion particles, so that the diffusion particles are evenly dispersed in the resin layer, and a part of the volume of the diffusion particles are exposed on a surface of the resin layer. Thus, the uniformity of the surface haze of the anti-glare coating can be enhanced, and flashing points of the display device can be avoided.
