PROBLEM TO BE SOLVED: To provide a magnetic display which enables the colorization of an image formed on a display surface and in which a color change by an angle to see is eliminated by eliminating the angle dependency of an interference color by converting a black color specific to a magnetic particle, an indispensable element as a formative element for a character or an image, into other various colors without using coloring materials, etc. SOLUTION: The magnetic display is formed by coating a microcapsule layer 7A enclosing the fine powders 5 of a light absorbing black magnetic material and the fine powders 6 of a light reflective nonmagnetic material which are dispersed in an oily dispersion liquid 4 between two nonmagnetic material substrates 2 and 3 one of which is transparent. An array layer 9A is arranged and embedded in the wall film 8 of a microcapsule 7 which encloses the oily dispersion liquid 4 of the fine powders 5 and the fine powders 6 so that planar particles 9 which form a multiplex layer structure to convert the black color specific to the fine powders 5 to be shown as the character or the image on the display surface 1 into the interference color are aligned in parallel with the wall film 8 throughout the spherical surface of the microcapsule 7.
