The present invention mainly relates to a backlight module for use in a
liquid display device. The backlight module comprises a plurality of
lamps located above a reflecting plate. Each lamp comprises two ends
while each end comprises an electrode. Voltage required for the lamps is
provided by at least one circuit board located at least one of two sides
of the reflecting plate; wherein the electrodes electrically connect to
the at least one circuit board directly. Sizes of the backlight can be
reduced in the present invention. Furthermore, costs of material and
manufacturing are also reduced.
