Abstract:
In a reflective liquid crystal display apparatus including a liquid crystal display element having a layer of liquid crystals contained in a plurality of cells capable of providing a particular orientation for the liquid crystals therein, and including a holographic reflector adjacent the liquid crystal display element, the improvement comprising the holographic reflector being a holographic recording film layer containing a plurality of first pixel volumes and a plurality of second pixel volumes, each one of the first pixel volumes including a first volume holographic mirror that reflects only light with a first color wavelength band, each one of the second pixel volumes including a second volume holographic mirror that reflects only light with a second color wavelength band, the first and second pixel volumes being positioned in the recording film layer such that light passing through each liquid crystal cell is reflected from both a first pixel volume and a second pixel volume.
