A green phosphor of the cold cathode fluorescent lamp includes BaMgAlO:Eu, Mn. The wavelength range of a green emission spectrum is located on a shorter wavelength side than that in the case where the green phosphor includes LaPO:Ce, Tb, so the spectral width of the green emission spectrum is narrower. Therefore, an overlap between the wavelength ranges of green display light and red display light is reduced. Moreover, the spectral characteristics of blue display light (blue spectral characteristics) are set so as to satisfy predetermined conditional expressions. An overlap between the wavelength ranges of the green display light and the blue display light is also reduced.

The present invention relates to a fluorescent screen forming method, a fluorescent screen forming apparatus and a cathode-ray tube. In the fluorescent screen forming method according to the present invention, a transfer roller lowers a transfer sheet to somewhere above the inner surface of the panel and the transfer roller moves up to the end edge positions of the inner surface of the panel, whereafter the transfer roller moves downwards onto the end edges of the inner surface of the panel in unison with the transfer film to start pressing the transfer film. Therefore, the transfer roller can reach the end edges of the panel, and hence component layers of a fluorescent screen can be transferred up to the end edges of the inner surface of the panel. A fluorescent screen forming apparatus according to the present invention includes a transfer film supply means, a transfer roller, and a control means, wherein operations of the above-mentioned transfer method are executed. As a result, it becomes possible to form a highly-reliable fluorescent screen. Further, a cathode-ray tube according to the present invention includes the fluorescent screen that has been formed by using the above-described transfer method. Thus, it is possible to provide a high-reliable cathode-ray tube of which the effective screen is large. Furthermore, when cathode-ray tubes are manufactured by using the above-described transfer method, the cathode-ray tubes can be produced more inexpensively.
