A fine multi-color image is scroll-displayed in a large size using a small number of light-emitting elements. Ten light-emitting element column sets Si (RCi.GCi.BCi) are linked like a belt to constitute a physical screen of a column of 16 dots by a row of 30 dots. The physical screen is regarded to be a virtual screen of a column of 16 dots by a row of 57 (=30 + 3 x 9) dots. In a given light-emitting element column set Si, when a red light-emitting element column RCi is control-driven by a column (k) of red data that are discretely selected, a green light-emitting element column GCi is control-driven by green data of a column (k + 1) next to the above selected column (k), and a blue light-emitting element column BCi are control-driven by blue data of the second next column (k + 2).
