Abstract
The display device includes a vacuum-tight envelope having a transparent front wall which is provided with a display screen. The display device comprises an internal selection structure (67) which is provided with holes and with a plurality of electrodes for addressing desired pixels on the display screen. The display device is provided with connection elements (71, 72) which each comprise a springy end portion (73, 74), which contacts an electrode (61, 62) on the selection structure (10), and which connection elements further comprise a feed-through portion (75, 76) to make an electric connection, through a wall of the envelope, between the electrodes (61, 62) and a voltage source situated outside the envelope. Preferably, the springy end portion (73, 74) includes a material which retains its springiness up to temperatures of at least 450.degree. C. for example a spring steel, and the material of the feed-through portion (75, 76) is adapted to the expansion of the material of the envelope. Preferably, the plates (60, 60', 60') of the selection structure (67) are displaced relative to each other in such a manner that the plates (60, 60', 60') do not overlap at locations where the springy end portions (73, 74) of the connection elements (71, 72) contact the electrodes (61, 62). During mounting, the connection elements (71, 72) are coupled to each other via a strip (85).
