A novel display mode called the mobile fine particle display (MFPD) is proposed. Fine particles doped and dispersed in nematic liquid crystals are used in our MFPD cell. The distribution of fine particles on a plane parallel to the substrate surface can be controlled by changing applied electric field, which is a DC field or an AC field adjusted by applying DC, to obtain optical changes in the MFPD cell. The velocity of fine particles is dependent on the electric force, dielectric force and friction force acting on the particles, and the flow of liquid crystals. The MFPD shows excellent characteristics such as a high reflectivity (approximately 50%), a high contrast ratio (more than 10), and a wide viewing angle. In addition, images displayed on the MFPD can be rewritten by the application of an electric field and be sustained under a no-voltage-application condition for a long time (over 5–7 months). The characteristics of the MFPD indicate that this new type of display is suitable for electronic paper displays.
