ABSTRACT:
A flat thin display device is obtained by means of cold cathodes (10) in which each cathode provides the electron emission (14) for a (part of a) column of pixels. The emissive surface is preferably chosen to be parallel to the front and rear walls (3, 4) of the display device so that the cathodes cannot degrade due to an ion bombardment.
