ABSTRACT:
A plurality of sign display units are arranged adjacent to each other along at least one surface in order to form a convex or concave arc curved surface curved with a predetermined radius. In each sign display unit, light-emitting elements are arranged in a dot matrix so as to be able to display a kanji character, a high-quality alpha-numeric character close to a printing type, or an image, thus displaying desired sign information. The sign display unit provides good readability while its visual field angle is increased without degrading the display quality.
