<P>PROBLEM TO BE SOLVED: To provide an antireflection coating in which breakage of an antireflective grid (AR grid) is prevented even when external pressure such as a pressing is applied from the outside and to provide an illuminator equipped with the antireflection coating. <P>SOLUTION: A large number of guard columns 4 are scattered in the AR grid 5 spreading on the surface of the antireflection coating 17. The guard columns 4 prevent a large number of projecting parts 30 constituting the AR grid 5 from being crushed when the antireflection coating 17 is pressed. When pressure is applied to the antireflection coating 17, a light emitting surface of a light transmission plate being in contact with the antireflection coating 17 comes into contact only with summit faces of the guard columns 4 which are higher than the projecting part 30 of the AR grid 5. Thus, even when excess pressure G is applied to the antireflection coating 17, the projecting part 30 is prevented from being crushed by contact of the light emitting surface with the AR grid 5. The guard column 4 is greatly useful to maintain a function of the antireflection coating 17. <P>COPYRIGHT: (C)2004,JPO |
