Abstract
In a light source inverter rectifier circuits are respectively connected to a CCFL in a substantially U-shaped lamp and a CCFL in a substantially U-shaped lamp, and the outputs from the rectifier circuits are fed to a stabilization circuit. Thus, the stabilization circuit monitors an average of currents flowing through the substantially U-shaped lamps. This makes it possible to make uniform the currents flowing through the substantially U-shaped lamps.

1-10. (canceled)
A light source inverter comprising:
- a plurality of transformers applying alternating-current voltages to a plurality of light-emitting lamps, respectively;
- a control section controlling electric power induced at secondary sides of the plurality of transformers;
- and
- a current detection section detecting currents flowing through two lamps, located apart from each other, of the plurality of transformers,
- wherein the control section controls the electric power induced at the secondary sides of the plurality of transformers based on the currents detected by the current detection section.
