(57) [Summary] In a device for displaying an image by moving particles by Coulomb force or the like, an electrostatic display device in which a display medium moves uniformly and achieves both improvement in stability and reduction in driving voltage. I will provide a. A transparent spherical spacer is disposed between opposed substrates, at least one of which is transparent, and a powdery fluid showing high fluidity in an aerosol state in which a solid substance stably floats as a dispersoid in a gas is sealed. The powder fluid is moved by Coulomb force or the like. |
