摘要

PROBLEM TO BE SOLVED: To make it possible to omit a developing stage, etc. to simplify the process and to form a uniform phosphor layer in tight contact with a cell surface, by using a photosensitive resin layer, which contains phosphors and is degraded in the tacky adhesiveness of exposed region in constituting a tacky adhesive photosensitive resin layer formed on one surface of a base material film. SOLUTION: The phosphor-contg. photosensitive resin layer 12 formed on the base material film 11 contains a relatively large amt. of phosphor. When the layer is exposed to UV rays, etc., through a photomask after the film is press-fitted into the cell, the tacky adhesiveness of the layer 12 to the base material film in the exposed regions at the boundary between the base material film 11 and the photosensitive resin layer 12 degrades drastically as compared with the tacky adhesiveness at the boundary in the non-exposed regions. The tacky adhesiveness at the boundary between the inside surface of the cell and the layer 12 is less degraded and the relation of tacky adhesiveness tacky adhesiveness tacky adhesiveness is resulted. Accordingly, when the base material film is peeled, the phosphor- contg. layer of the non-exposed regions may be removed from the inside of the cell and the phosphor-contg. layer of only the exposed regions may be packed into the cell. The need for the developing stage is thus eliminated.
