ABSTRACT:
A chip-in-glass type vacuum fluorescent display device includes an integrated circuit chip for driving a display unit in a vacuum glass envelope. The integrated circuit chip is connected to plural number of external terminals to be supplied with an electric power from an external power supply, so that resistances of the external terminals themselves, and those of the connecting points of the external terminals and conductor patterns which connect the terminals to the integrated circuit chip. As a result, the potential change at pads of the integrated circuit chip, which causes unstableness in operation of the integrated circuit and changes of characteristics thereof, is decreased.
