Abstract
A display medium of the present invention includes first and second substrates, a spacing member and a particle dispersion liquid. The first substrate is transparent to light. The second substrate is opposite to the first substrate and has plural electrodes placed at an interval. The second substrate has a difference between reflectivity of the electrode portions and reflectivity of plural boundary portions between the electrodes with respect to light incident from the first substrate side. The difference is 12 percentage points or less. The spacing member is placed between the first and second substrates at another interval, is transparent to light, and keeps a gap between the first and second substrates. The particle dispersion liquid is filled between the first and second substrates, and includes particles moving in a direction of an electric field formed between the first and second substrates and a dispersion medium.
