ABSTRACT:
A magnetic display panel which includes a multicell structure between two substrates is described. The cells are filled with a dispersion liquid including magnetic particles, a dispersion medium, and a thickener or the like, and a colorant can also be included in the dispersion liquid. The multicell structure and substrates are made of nonorientational and uncrystallized polyester resin. The magnetic display panel formed by such polyester resin is superior in display definition, non-deterioration ability, strength and the like.
