PURPOSE:To obtain the reflection mirrors for projection televisions which decreases the generation of double images and are inexpensive by applying an antireflection layer consisting of a polymer having a fluorine-contained aliphat. cyclic structure on the reflection mirror. CONSTITUTION:The antireflection layer 8 consisting of the polymer having the fluorine-contained aliphat. cyclic structure is applied on the reflection mirror. Incident rays 4 are partly reflected by the antireflection layer 8 or glass plate 2 in such a case but the 1st auxiliary rays 6 are slight as the refractive index of the antireflection layer 8 is low. The greater part of the incident rays 4 are reflected by a reflection layer 3 consisting of a silver layer, vapor deposited aluminum layer, etc., and are reflected as main rays 5 through the glass plate 2 and the antireflection layer 8. Further, the reflected rays from the reflection layer 3 are partly reflected by the boundary face of the glass plate 2 and the antireflection layer 8 or the surface of the antireflection layer 8. These rays are reflected by the reflection layer 3 and are projected as the 2nd auxiliary rays 7. However, these 2nd auxiliary rays 7 are also slight as the refractive index of the antireflection layer 8 is low. |
