Patent number: 6249266Abstract: A fluorescent display device including a planar cathode is provided which is capable of carrying out setting of an interval between a cathode and an anode and alignment therebetween with high precision. A cathode substrate having an FEC formed thereon is mounted through a lead frame on support members. Lead wires of the lead frame are abutted against bumps on the cathode substrate. An anode substrate having a holding frame attached thereto is positioned with respect to the cathode substrate and the holding frame and lead frame are fixed to each other. Both substrates thus temporarily fixed to each other are combined with a casing while keeping the cathode substrate facing down. Then, the anode substrate and casing are sealedly connected to each other.Type: GrantFiled: August 14, 1995Date of Patent: June 19, 2001Assignee: Futaba Denshi Kogyo K.K.Inventors: Takao Kishino, Hisashi Nakata
