[Invited Paper] Wide-Color-Gamut Reflective Color LCDs using Double-Layered Directional Light Diffusion Film

抄録

We have developed a reflective color liquid crystal display with high reflectivity of 60% and a good contrast ratio of 50:1, and a wide color gamut of 50% of NTSC color standards. We fabricated two light diffusion layers with different diffusion angle range in a single polymer film by using two-step UV irradiation process and achieved high reflectivity across a wide angle range. Our reflective display has a high image quality as well as a low power consumption, therefore it is expected to contribute to the development of future low power display applications including smart watches, e-book readers, and digital signages.
