A Mobile Fine Particle Display (MFPD) which was proposed in a first place by our group is based on the electrophoresis effect of fine particles in nematic liquid crystal that used as an anisotropic solvent. In the MFPD cell, the images are displayed due to control the amount of fine particles in a pixel area by an applied voltage. Since the displayed images are permanently memorized, the MFPD has a possibility to be utilized as an electronic paper.In the present stage, the contrast ratio obtained in MFPD is not sufficiently high enough, since MFPD needs an accumulation space of fine particles in a pixel. In this study, a three-layered structure is newly proposed to improve the contrast ratio of MFPD cells.
