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.
