摘要:
An information display device has an information display plate where at least one or more kinds of particles are sealed between cells formed by a partition wall, the cells being between two opposite substrates at least either of which is transparent. At least either of electrodes is provided on a substrate, and an electric field is applied to the particles by the electrodes to move the particles, causing information such as an image to be displayed on the display plate. The surfaces of the substrates are smoothed by making D≧2H satisfied, with D being the diameter of a particle (a particle forming the particles), H the height of the electrodes. This thins the electrodes as much as possible (making the height of the electrodes small) and smoothes the surfaces of the substrates, and as a result, the information display device after an endurance test has an improved contrast ratio.
