Abstract

Polymer dispersed liquid crystal (PDLC) can be realized as the brighter display compare to conventional LCD because polarizer is unnecessary. We newly proposed a full colour photoluminescence-polymer dispersed liquid crystal (PL-PDLC) which PL materials including red, green and blue PL were added to PDLC, and investigated the colour gamut and the reflectance functioning as applied voltage. We confirmed that our full colour PL-PDLC presented the 12.5% of the reflectance and the 28.8% of color gamut on the basis of National [US] Television System Committee (NTSC). It could be suggested as a potential method to fabricate the high performance and the low cost full colour reflective liquid crystal display without a colour filter and a polarizer.
