WIPO Patent Application WO/2008/015831
Kind Code:
A1
Abstract:
An illumination device for a display device has cold cathode tube lamps (1) capable of
being parallelly driven, a first holding member (3) having holders (2) equivalent in
number to the number of the cold cathode tube lamps (1) and each holding one end of
each lamp (1), a second holding member (5) having holders (4) equivalent in number
to the number of the cold cathode tube lamps (1) and each holding the other end of
each lamp (1), and an electric power source device (6). Harness lines (7, 7')
connected to one end of the electric power source device (6) and the first holding
member (3) are interconnected at multiple points, and harness lines (8, 8')
connected to the other end of the electric power source device (6) and the second
holding member (5) are interconnected at multiple points. This reduces uneven
brightness. The illumination device for a display device can be used as backlight
for a liquid crystal TV.
