Abstract

To provide a magnetic display in which a character or image of a black color formed of magnetic fine particles such as black iron oxide fine particles may readily be changed into a variety of interference colors with a simple structure without deteriorating a function of a conventional magnetic display. A microcapsule layer containing and sealing light-reflective non-magnetic fine particles and black magnetic fine particles dispersed in an oily liquid is coated in a space between two non-magnetic substrates at least one of which is transparent to form a display sheet, a magnetic field for forming a character or image is applied from a surface of the display with a transparent substrate side being a front surface side thereof and a magnetic field for erasing the character or image is applied from a back surface thereof so that positions of the black magnetic fine particles and the light-reflective non-magnetic fine particles within the microcapsules are inverted to thereby form the character or image. A pearl pigment layer exhibiting a variety of interference colors is applied onto the front surface or the back surface of the transparent substrate.
