Abstract: The present invention provides an antiglare film, which includes a transparent resin layer, a plurality of transparent hollow particles and a plurality of transparent solid particles. The hollow particles and the solid particles are distributed in the transparent resin layer, while the hollow particles are partially exposed thereon. The refraction index of the hollow particles and the refraction index of the solid particles are different from the refraction index of the transparent resin layer. Applying both the solid particles and the hollow particles mixed together can lead the antiglare film to have an excellent antiglare property, a high contrast and a great clarity.
