Abstract

A pressure-sensitive display medium includes a pair of transparent substrates, sealing members and a display layer. The pair of transparent substrates are opposed to each other with a distance therebetween. The sealing members seal peripheral fringes of the pair of transparent substrates. The display layer in which a composition obtained by infiltrating a fluidic material in a porous member is filled in a closed space enclosed with the pair of transparent substrates and the sealing members. When partial pressure is applied from the outside to one face of the transparent substrates, the fluidic material in the display layer at a position to which the pressure is applied is expelled from the porous member. After the pressure is released, the fluidic material having been expelled returns and flows into the porous member.
