We demonstrate full-color cholesteric liquid crystal films fabricated by cholesteric liquid crystal and reactive mesogen. The reflection linewidth of these films can be dramatically narrowed with the reduced refractive index birefringence of refilled materials. A full-color reflective display is experimentally demonstrated based on these reflective films that are refilled with small birefringence liquid crystals. The electro-optic performances of displays including response time are experimental investigated. The applications of these films include flexible reflective display, color pixels in digital photographs, printing and colored cladding of variety of objects.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
