The colored layer (12) colors the light which is reflected by the reflecting layer to travel to the observer in the color of the colored layer. Here, the reflecting layer is arranged only in an area where the colored layer should be arranged, so light which does not pass through the colored layer is not reflected and then never travels to the observer. An unnecessary reflected light component can, therefore, be prevented from being generated by the reflecting layer. Consequently, no black matrix needs to be provided to prevent the unnecessary reflected light component from being generated.  <P>COPYRIGHT: (C)2003,JPO
