A backlight assembly including a lamp having a lamp tube and first and second conductive members, a container body exposing the lamp tube while covering the first and second conductive members, a power-supplying means receiving the first and second conductive members and providing them with power, and a light uniformity improving means. A liquid crystal display panel assembly is coupled to the backlight assembly so as to display a picture by controlling a transmittance of the light passing through the light uniformity improving means.

Liquid crystal display device including a cold cathode fluorescent lamp and a container for receiving the same

Disclosed are a lamp, a method of fabricating the same and an LCD having the same. Electrode is disposed on an outer surface of a lamp tube, and an adhesive member is interposed between the electrode and the lamp tube. The adhesive member is hardened and expanded by means of heating, and adheres the electrode to the lamp tube. Thus, voids generated during forming the electrode on the outer surface is removed, and images having a high quality are obtained.

Lamp, method of fabricating the same and liquid crystal display apparatus having the same

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

Disclosed are a backlight assembly and a liquid crystal display device using the same. A ratio of a pitch, which is an interval between the lamps for supplying light to an LCD panel, to a gap, which is a distance between the center of the lamps and an optical plate, is adjusted to thereby minimize the bright line that badly influences the image display quality, so as to display a high quality image.

Backlight assembly and liquid crystal display device using 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.
