CCFL for use in LCD backlight and manufacture thereof

摘要

This invention is a fluorescent lamp for a backlight of a liquid crystal display device which can improve the lifetime and luminous efficiency (CCFL: Cold Cathode Fluorescent Lamp) and to a method of manufacturing the same. In a fluorescent lamp according to the fluorescent material is applied to the inner wall and comprises two electrodes arranged at each end of the glass tube and the glass tube containing a discharge gas inside the lamp, as through lead electrically connected to the outside, where the each electrode of the fluorescent lamp includes a first opening side region and a second intermediate region and a third region that is associated with the closing side in the lamp lead glass tube such that the outside is in contact with the glass tube, the glass tube is completely sealed in the glass tube is inserted into the and, the diameter of the first open-side region is smaller than the diameter of the glass tube, the diameter of the third closing side region thereof is formed to be larger than the diameter of the glass tube.
