Claims

1. A backlight device comprising: a lamp; an inverter circuit that generates from an inputted voltage a drive voltage for driving the lamp; a socket section that holds an end part of the lamp and applies the drive voltage to an electrode lead led out from the end part of the lamp; and a metal chassis,
the socket section comprises a dielectric between a flat part of the electrode lead of the lamp and the metal chassis, and
the electrode lead, the dielectric and the metal chassis function as a resonant capacitor of an output transformer of the inverter circuit.
2. The backlight device according to claim 1, wherein the dielectric is a removable dielectric unit.
3. The backlight device according to claim 2, wherein the dielectric unit comprises a solid dielectric material and holding sections for holding the solid dielectric material.
4. The backlight device according to claim 2, wherein the dielectric unit comprises a liquid dielectric material and a container into which the liquid dielectric material is injected.
5. The backlight device according to claim 1, wherein the dielectric unit is selected in accordance with a voltage characteristic of the lamp so as to adjust the capacitance of the resonant capacitor.
6. The backlight device according to claim 1, wherein the electrode lead has a flat part formed by flattening at least one part of an electrode line.
7. The backlight device according to claim 1, wherein the electrode lead has a flat part formed by connecting a flat metal plate to an electrode line.
8. The backlight device according to claim 1, wherein the lamp is a cold cathode fluorescent tube.
9. A display device comprising a display section and the backlight device according to claim 1,
the display section is irradiated with light from the backlight device.
