| 摘要 |
A driving apparatus for a plasma addressed liquid crystal display has a reference voltage selection D/A converter (27) for applying a driving voltage to a first transparent scanning electrode group, a common anode inversion driving voltage generator (30) for applying a common anode inversion driving voltage obtained by relatively inverting a driving voltage to a second electrode scanning electrode group, and a contrast reduction adjustor (42) for simultaneously tracking a voltage on a low voltage side when a reference voltage is not inverted in the reference voltage selection D/A converter (27) and a power-supply voltage on a high-voltage side at the time of inversion, and adjusting the voltages so as to adjust reduction in contrast.
