ABSTRACT:
To provide a discharge lamp lighting device in which the initial state of discharge in a wiring of a circuit on the secondary side of a transformer in the discharge lamp lighting device is accurately detected and the operation thereof stops and which can be applied to a large-scaled liquid crystal display device. The discharge lamp lighting device according to the present invention includes a transformer5, a transformer drive circuit4, and a control circuit3for controlling the transformer drive circuit4. The transformer drive circuit4drives the primary side of the transformer5, and a discharge lamp6is lit on by being connected to the secondary side of the transformer5. The discharge lamp lighting device further includes a discharge detecting pattern13having one end connected to the ground and the other end connected to the control circuit3, and means that detects a voltage induced by electromagnetic waves received by the discharge detecting pattern13and stops the power supply to the secondary side of the transformer5, and at least one part of the discharge detecting pattern13is disposed adjacent to a portion of a high-voltage wiring of a circuit on the secondary side of the transformer5.
