MAGNETIC MATERIAL-INVERTING DISPLAY PANEL

摘要

A magnetic material-inverting display panel which provides a clear display and the erasure by having a liquid dispersion, which has a predetermined yield value and contains a magnetic display material in fine particle form having magnetic poles of opposite signs tinged with different colors. The liquid dispersion also includes a dispersion medium and a thickener as main components, and is supported by a supporting member. The total area of S-pole-surfaces or N-pole-surfaces of fine particles of the magnetic display material being from 60 to 500% of the display surface area of the display panel.
