<p>A driver circuit which drives a flat panel display. A constant-voltage element (16) generates a gate bias of an MOS transistor (11) which electrically charges the output terminal (23) to a high level, and a current that flows into the constant-voltage element (16) is controlled by a current control circuit (25). The charging current electrically charges the output terminal (23) via a diode (15). To turn the charging MOS transistor (11) off, an MOS transistor (13) is turned on to discharge the node of gate of the MOS transistor (11). When the output is to be switched, a drive signal generating circuit (30) produces drive signals (S1, S2) that have a period for turning off both the charging MOS transistor (11) and a discharging MOS transistor (12) that discharges the output terminal (23) to a low level.</p> |
