Title:
BACKLIGHT DEVICE, LIQUID CRYSTAL DISPLAY DEVICE, METHOD FOR ASSEMBLING BACKLIGHT DEVICE AND SUBSTRATE DEVICE FOR CONNECTING FLUORESCENT TUBE
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.
