PROBLEM TO BE SOLVED: To provide a low-cost antireflection films of superior antireflection performance and of mechanical strength and alkali resistance. SOLUTION: The antireflection film is obtained by stacking a hard coat layer 3, a high-refractive index layer 2 and a low-refractive index layer 1 on the surface of an organic film 4. Each of the layers 1-3 based on a synthetic resin, such as an acrylic resin. The layer 2 is provided with a high-refractive index by incorporating fine metal oxide particles having high-refractive index. The layer 1 is made porous, by incorporating fine particles 5 of a metal oxide or a fluororesin in large quantities so as to fully lower the refractive index. |
