ABSTRACT:
The present invention relates to holographic multicolor optical elements for use as multicolor filters in liquid crystal displays and methods of making the elements. The elements can be used as multicolor reflective or transmission filters The elements can have one, two, three or more holographic recording film layers Each layer comprises at least first and second pixel volumes containing holographic mirrors and preferably third pixel volumes containing a holographic mirror.
