Abstract:
1. An antireflection film comprising: an organic film, a hard coating layer coated on the organic film, a first layer having an index of refraction and coated on the hard coating layer, said first layer being formed of a synthetic resin having pores therein and metallic oxide particles contained in the synthetic resin, said metallic oxide being at least one selected from the group consisting of ZrO a second layer having an index of refraction lower than that of the first layer and coated on the first layer, said second layer partly entering into the pores to firmly bond to the first layer through the pores, wherein said first layer comprises a porous precursory layer having an index of refraction not greater than 1.64 and said second layer comprises a liquid material coated on the porous precursory layer made integral with pores of the porous precursory layer so that when the first and second layers are integrally formed, the first layer has the index of refraction not smaller than 1.64.
