Magnetic material-inverting display panel

A magnetic material-inverting display panel comprising a support that supports a liquid dispersion having a yield value and containing magnetic display material in a particle form, a dispersion medium and a thickener as main components;

• the particles of magnetic display material comprise first and second surfaces, at least the first surface comprises an opaque metal vaccum evaporation layer having a first color, the second surface is tinged with a second color which is different from the first color, the first surface has a first magnetic pole and the second surface has a second magnetic pole which is opposite to the first magnetic pole;
• the particles of magnetic display material are formed by cutting or pulverizing a laminate which comprises a magnetic layer having third and fourth surfaces, a thin opaque metal vaccum evaporation layer formed on the third surface in the first color, and the fourth surface tinged with a second color;
• the magnetic layer comprises magnetic particles dispersed into a synthetic resin and/or synthetic rubber composition;
• the support has an inner volume of V, the magnetic display material has a volume of W, and a first ratio between the inner volume V and the volume of the magnetic display material W/V×100 is 1 to 17%;
• and
• a total area of one of the first and second surfaces is from 50 to 1500% of a display surface area of the display panel.
