要約
(EN)
The size of a backlight device, including an inverter circuit board, is reduced as a whole and cost is reduced. The backlight device is provided with a lamp (20a); an inverter circuit for generating a drive voltage for the lamp (20a) from an inputted voltage; a socket section (26a), which holds an end section of the lamp (20a) and applies the drive voltage to an electrode lead (28a) led out from the end section of the lamp (20a); and a metal chassis (31). The socket section (26a) is provided with a dielectric material (32) between a flat surface section of the electrode lead (28a) of the lamp (20a) and the metal chassis (31). The electrode lead (28a), the dielectric material (32) and the metal chassis (31) function as a resonant capacitor of an output transformer of the inverter circuit.
