In a lamp and method for fabricating the same, an outer surface of the lamp tube is dipped into a conductive transparent solution for forming an electrode by a predetermined depth, and then the lamp tube is pulled out from the solution. Accordingly, an electrode having different profiles is formed on the outer surface of the tube body. Also, the outer surface of the lamp tube is dipped into the solution by an acute angle, and is pulled out from the solution. Therefore, a problem of a nonuniform brightness between lamps is not generated, and light utilization efficiency is much enhanced even when using a plurality of lamp in parallel connected to a power supply.

Lamp and method of manufacturing the same

A backlight assembly has a light diffusion member including a diffusion layer for diffusing first light emitted from at least one lamp and a light path modulation layer formed on the diffusion layer to modulate the path of the first light, Therefore, the light diffusion member emits second light having uniform distribution of the brightness. The light path modulation layer may be disposed on one surface of the diffusion layer where the first light is input, or another surface of the diffusion layer where the second light is emitted.

A light source device for preventing a light guide plate from being discolored due to a light supplied by a lamp is disclosed. At least one masking film that is made of a transition metal oxide is disposed in a pathway of the light that is emitted by the lamp and transmitted to a display unit to display images in order to cut off ultraviolet rays having particular wavelengths capable of discoloring the light guide plate. Accordingly, it is possible to prevent the light guide plate, which is made of polyolefin resin composition to make it lightweight, from discoloring in yellow.

Light source device for flat panel device

Disclosed is a light source device capable of minimizing leakage of power supplied to a lamp of a liquid crystal display device. A plurality of power supply lines is extended between the lamp for generating light and an inverting board for receiving the power source from the outside to supply power to the lamp. The plurality of the power supply lines is coated with a shrinkable tube to be spaced apart from one another. Accordingly, the leakage of the power source that is generated from the first, second, third and fourth power supply lines due to a coupling phenomenon thereof is minimized.
