PLASTIC MEMBER WITH ANTIREFLECTION FILM AND ITS PRODUCTION

Japanese Patent JP3769039

B2

PURPOSE: To obtain a plastic member with an antireflection film which has excellent adhesion property, durability and little variation in the antireflection performance and can be easily mass-produced by using an aluminum oxide layer having low refractive index as an adhesion layer between the plastic member and magnesium fluoride.
CONSTITUTION: On the surface of a plastic member, an antireflection film of a two-layer structure comprising a first layer and a second layer from the surface to the air side is formed. The first layer is an aluminum oxide layer 6 while the second layer is a magnesium fluoride layer 7. The refractive index of the aluminum oxide ranges from 1.49 to 1.54. Any plastic material can be used unless the refractive index exceeds 1.55. When a polarizing plate 5 is used as the plastic member, reflection of light on the surface can be prevented and a sharp display with good contrast is possible.
