Abstract
A flat panel display device includes a face plate made of a transparent material, a back plate positioned parallel to the face plate, and a wall member extending between the face plate and back plate to define an airtight housing. An anode is provided on a inner surface of the face plate, a fluorescent layer is provided in association with the anode, and a cathode is provided in association with an inner surface of the back plate. A plurality of struts, made of an electrically conductive screen printed powdery material, are tightly held between the back plate and the face plate, such that an electric charge accumulated between the anode and cathode is discharged by a leakage current flowing through the struts.
