摘要： To provide a gas discharge display device that can perform stable write operations for a gas discharge panel and thereby display images with superior quality. A base pulse is applied throughout a write period. The base pulse gradually varies with an approximately constant slope (an average slope of 10V/&mgr;sec or less), during an introduction part Ia (i.e. from when the leading edge of the base pulse starts until immediately before the base pulse reaches a constant base voltage Vb) of the write period. A scan pulse Psco is not applied in the introduction part Ia, but is applied after the base pulse reaches the base voltage Vb.
