Waveguide liquid crystal display (WLCD) is a newly developed transparent display technology. Since polarizers and color filters are not necessary for the WLCD, high transparency is easily reached. Meanwhile, owing to the fast response time, field sequential color (FSC) can be applied to realize full color display. In this work, by optimizing materials and process conditions, we obtained lower driving voltage and higher contrast ratio than previously reported. These enhanced characteristics provide the possibility for designing larger size panel. Finally, we have developed an 8 inch full color transparent WLCD prototype and discussed the upgrading methods to improve brightness uniformity.
