Abstract
A fluorescent display device (1) includes an air tight envelope (2) having a cathode substrate (3), an anode substrate (4) with a phosphor layer arranged to provide a luminous display, a seal member (5), an evacuation hole (9) formed at a side of the envelope (2), and a getter chamber (10) in communication with the hole (9). The getter chamber (10) is disposed on the outside of the envelope (2) and includes a chamber body (12), and an evacuation tube (13). The getter chamber (10) eliminates the independent formation of an evacuation hole in the cathode substrate (3), and thereby prevents damage and contamination of the cathode substrate (3).
