Document Type and Number:
WIPO Patent Application WO/2008/007560
Kind Code:
A1
Abstract:
A fluorescent tube is prevented from being wrongly attached and broken when being attached, and luminance nonuniformity of backlight due to luminance difference generated in a tube axis direction of the fluorescent tube is reduced. A backlight device (2) is provided with a plurality of fluorescent tubes (21) having electrodes (211) on the both ends; a bundling member (213) for bundling wirings (212) lead out from the electrode (211) on one side of two or more of the fluorescent tubes (21); and a current carrying means (31) for carrying a current between the electrodes of the two fluorescent tubes among the fluorescent tubes (21) by being connected with the bundling member (213). The current carrying means (31) permits a current to be carried between the electrodes of the two fluorescent tubes (21), which are bundled by the one bundling member (213), and the current carrying means are arranged on inverter circuit boards (28), respectively, not to be adjacent to each other.
