ABSTRACT:
In a field emission type cathode structure for a CRT, a grid electrode has an opening at a position corresponding to a position of a bonding wire for connecting a gate electrode to a lead connected to a power supply for a gate voltage. A bonding tool moves vertically through the opening of the grid electrode to bond the bonding wire on the gate electrode and the lead.
