ABSTRACT:
An inverter circuit for a backlight device includes an inverter transformer which supplies a high AC voltage to a plurality of discharge tubes, a filter circuit connected to an output terminal of the inverter transformer, and an abnormal discharge detection circuit. The filter circuit passes a current signal having a high frequency component of the high AC voltage to the abnormal discharge detection circuit, and the abnormal discharge detection circuit detects an abnormal discharge current based on the current signal.
