Abstract:
1. A magnetic migration and reversal display panel comprising at least a dispersion liquid having a yield value obtained by dispersing, in a dispersion medium comprising a colorant, micro-magnets having magnetic poles that differ in color and that differ in color from the dispersion medium as well, and support members that retain the dispersion liquid, wherein each of the micro-magnets comprises two or more kinds of magnetic materials with different coercive forces including a first magnetic material consisting of a high coercive force material having a coercive force of from 65.0 kA/m to 600 kA/m, and a second magnetic material consisting of a low magnetic coercive force material having a coercive force of from 0.8 kA/m to less than 65.0 kA/m.
