Abstract(in English) Recently, as the LCD size becomes larger, the diameter of the CCFL which is used as the backlight becomes bigger and the length of the CCFL becomes longer. The CCFL for the large size LCD is required for the high luminance, the long life time, the decrease in the chromaticity variations at the both ends of the CCFL, and the high efficiency. In this paper, the CCFL's characteristics depended on the phosphor layer condition are investigated. As the diameter of the lamp becomes bigger, the UV rays density irradiated on the phosphor becomes more thin. By conditioning the size of the phosphor particle and the thickness of the phosphor layer, the UV rays are led to the phosphor layer's depth portion, and the 3% improvement of the CCFL's luminance are realized.
