“…We optimized exposure doses of linear polarized ultraviolet (UV) light and baking conditions. The isomerization type PA layer material was selected as we presumed that the isomerization type PA material does not generate photolyte during UV exposure process [5], as depicted in Figures 1(a) and 1(b). The fact implies that the impurity derived from the PA material does not generate.…”

We have developed a novel photo-alignment FFS-LCD (PA-FFS-LCD) with a wide nematic temperature range from -40°C to 95°C. Our developed PA-FFS-LCD shows fast gray-to-gray response time (< 20 ms at 25°C and < 300 ms at -30°C), wide viewing angle, and high contrast ratio over 1500. Image sticking was not recognized owing to a suitable configuration of pixel and common electrodes. The developed LCD can be used for vehicular application.
