BACKLIGHT DEVICE, LIGHT SOURCE LIGHTING CIRCUIT BOARD AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A frame is narrowed by a technically reasonable design, without technical limitation for frame narrowing which tends to be considered troublesome when bent-tube type fluorescent tubes having U-shaped bent portions are to be alternately arranged to face each other nor without the trouble of storing the bent-type fluorescent tubes in a chassis while being manufactured. A backlight device (2) is provided with a backlight chassis (23) wherein a plurality of fluorescent tubes (21) having electrodes are arranged and stored, and an inverter circuit board is arranged on the rear surface of the backlight chassis (23). Furthermore, the backlight device (2) is provided with a storing section (30), which is attached to the backlight chassis (23) by storing a conductive holding section for holding the electrodes. With the storing section (30) attached to the backlight chassis (23), the electrodes of the fluorescent tubes (21) are electrically connected to a light source lighting circuit board arranged on the rear surface of the backlight chassis (23).
