Abstract
A display medium includes a first substrate that is transparent to light, a second substrate, a spacing member, and a particle dispersion liquid. The second substrate is provided to be opposite to the first substrate and has a plurality of electrodes placed at a predetermined interval. The spacing member (i) is placed between the first and second substrates at another interval different from the predetermined interval of the electrodes, (ii) has a first end portion on a first substrate side of the spacing member and a second end portion on a second substrate side of the spacing member. The first end portion is transparent to light. The second end portion has different transparency from the first end portion to reduces a reflection of light incident through the first substrate onto a first substrate side of the spacing member.
