Abstract: According to the present invention, in a thermosensitive transfer film F in which at least a fluorescent substance layer 3 and an adhesive agent layer 4 are deposited onto a base film 1, this adhesive agent layer 4 is produced by mixing at least a pigment corresponding to a color of the fluorescent substance layer 3, a thermosensitive agent and a photosensitizer. Also, a display device manufacturing method comprises the steps of forming patterning by exposure and development and using the adhesive agent layer 4 as a color filter layer after the fluorescent substance layer 3 and the adhesive layer 4 have been transferred onto the inner surface of the display panel from this thermosensitive transfer film F. Thus, in the thermosensitive transfer film in which layers are formed by the transfer process, work efficiency of the transfer process can be improved, and the sharp pattern can be formed.

Abstract: 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.
