To provide a safe display device which can easily pattern characters, graphics, symbols, etc., on a pedestal in three-dimensions or in plane with a linear light source, can be used repeatedly many times, can make an emphasized display, etc., of interior decoration with small power consumption, eliminates the need for soldering, and can be used for teaching materials.

A-rubber terminals 3 are fitted in respective elements of a display character of an EL fiber 2, a core electrode is inserted from the tip to the root into an insertion hole 10a machined matching the display character on the pedestal 10, and a B-rubber terminal 4 is inserted into the core electrode projecting penetrating the pedestal 10. The free end of the projecting core electrode is bent in parallel to the reverse side of the pedestal 10 and made to meet a slit and then an additional electrode is pressed against a 1st conductive member in contact across conductive rubber. Further, the core electrode is pressed against a 2nd conductive member in contact across conductive rubber to obtain conduction up to an input terminal 6.
