    • PROBLEM TO BE SOLVED: To provide a microcapsule magnetophoresis display which can increase the choices of dispersion mediums to be included in a microcapsule, allowing use of a dispersion medium haivng higher safety, producing the microcapsule achieving excellent performance by high yield, and achieving excellent contrast, durability, safety, and productivity. SOLUTION: This microcapsule magnetophoresis display is constituted by encapsulating the dispersion liquid prepared by dispersing two components, namely, light-absorptive magnetic particles and light-reflective non-magnetic particles in an oily dispersion medium in the microcapsule, arranging the microcapsules on a substrate, moving the mutual positions of the two components in the dispersion medium vertically in the microcapsule by a magnetic field to be applied from the outside of the substrate to form characters or images or erase them. The dispersion medium of the internal liquid of the microcapsule is one or two or more kinds of oily liquids having a flash point of 70°C or more, a volume density at 15°C of 0.75-0.91 g/cm 3 , and a dynamic viscosity at 40°C of 7 mm 2 /S or less. 0.5-8.0 wt.% of a nonionic surface active agent which is liquid at normal temperature with an HLB value of 5.0 or less is added to the internal liquid, and solid particles having particle diameter of 0.1-30 μm and a true specific gravity exceeding 1.0 are added to the internal liquid of the microcapsule to increase volume density of the internal liquid, thereby adjusting the volume density of the internal liquid of the microcapsule at 15°C to 1.0-1.2 g/cm 3 .
