In general, a liquid crystal display displays a number or an image by injecting a liquid crystal, which is an intermediate material between a solid and a liquid, between two thin glass plates and changing the arrangement of liquid crystal molecules by a voltage difference between upper and lower glass plate electrodes. It is an element to make.

In particular, the liquid crystal display device has the advantages of light weight, slim type, low power consumption and low voltage driving as compared to the CRT (Cathode Ray Tube) has been widely used in electronic products such as electronic clocks, electronic calculators, liquid crystal TVs, notebook PCs.

Since the liquid crystal display device is a passive display device which does not emit light by itself, a backlight unit for illuminating the liquid crystal display device is provided on the rear or side surface of the liquid crystal display device. The backlight unit uses a direct lighting method, a side edge lighting method, a hybrid lighting method and the like according to the position of a light source, that is, a fluorescent lamp.

In addition, the fluorescent lamp as the light source has been mainly used Cold Cathode Fluorescent Lamp (CCFL) having an electrode inside both ends, but recently, an electrodeless fluorescent lamp (EEFL) having an electrode at both end surfaces. External Electrode Florescent Lamp has been developed.

Since the electrodeless fluorescent lamp has no direct collision between the electrode and the ion, the heat generation of the electrode is not only suppressed, but is driven by a high voltage and a low current, thereby generating less plasma joule heat, and has a unique phenomenon called self-discharge. It has advantages such as high brightness and high efficiency driving.

Therefore, there is an urgent need for the development of an electrical connector for electrically connecting the electrodeless fluorescent lamp.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electrodeless fluorescent lamp electrical connector of a backlight unit for a liquid crystal display device capable of easily connecting an electrodeless fluorescent lamp electrically.
