Abstract: A composition of an anti-glare coating has a resin, multiple particles and a dispersant. The resin is selected from the group consisting of thermosetting resin and light-curing resin. The particles have a dimension that is from about 30 nanometers (nm) to about 10 micrometers (?m). Because the dispersant stabilizes and keeps a separation distance between each two particles, the particles cannot aggregate in or precipitate out of the anti-glare coating. Thus, the anti-glare coating can be coated easily on the substrate and a surface of the anti-glare film is uniform to provide an improved anti-glare effect. Moreover, the dispersant allows adjustment of haze, gloss and distinctness of image of a substrate coated with the anti-glare coating.
