A lamp assembly for a liquid crystal display device includes a lamp tube for
generating
light, and electrodes each having a suitable shape for receiving end portions of
the lamp tube. The lamp tube and the electrodes are combined to generate the light
by applying electric power to the electrodes. The lamp assembly may include multiple
lamp tubes having different brightness from each other, in which the brightness
difference between the lamp tubes is compensated by uniformly diffusing the light
generated from the lamp tubes.
