SOLUTION: Right and left longitudinal front signboards are cross-disposed like a forward projection, the back of a space surrounded by both front signboards is covered with a back plate to form a hollow display tower shaped substantially like a triangle pole. The right and left longitudinal boards where light emitting elements are arrayed in a plurality of vertical columns and in a plurality of lateral rows are arranged side by side with the left signboard and the right signboard, and the light emitting elements of the columns and rows in the left board and the light emitting elements of the columns and rows in the right board are controlled to emit light by a control part.
