Abstract:
A display apparatus includes a first substrate provided with a plurality of closed containers, a fluid filled in the closed containers, a plurality of positively charged particles which have a relative dielectric constant different from the fluid and are dispersed and held in the fluid, a plurality of negatively charged particles which have a same color as the positively charged particles and a relative dielectric constant different from the fluid and are dispersed and held in the fluid, and a pair of electrodes for generating an electric field in the closed containers. The display apparatus displays an image formed by a positional distribution of positively and negatively charged particles in each of the closed containers.
