Display medium

A display medium comprising:

• a pair of substrates that have light transmittance;
• electrode members that are respectively formed on opposing surfaces of the substrates, have light transmittance, and are capable of carrying an electric current;
• a display member that is interposed between the electrode members and displays display information when the electric current is supplied;
• a terminal portion that extends from at least one electrode member;
• a reinforcing portion that has electrical conductivity and is joined to the terminal portion;
• and
• a mounted electrode provided so as to be substantially parallel to and face the terminal portion;
• and
• a joining portion that has electrical conductivity and is formed with a joining material that has a cohesive force after curing larger than that of the reinforcing portion, the area of a reinforcing joining region of the terminal portion to which the reinforcing portion is joined being smaller than the area of a mounted joining region of the terminal portion to which the joining portion is joined.
