In addition, in order to form the symbol arrangement pattern (13) among the plurality of cells in the code space (11), cells (12) in which pattern elements (15) have been placed are turned on, and cells (12) in which pattern elements (15) have not been placed are turned off. A display code (1) in which added information that is different from the message is added to a symbol parameter which is binary information specified by the on-off states is attached to an article.
