Abstract:
A method for forming a fluorescent substance pattern for a fluorescent display device, said method, comprising the steps of:laminating onto the surface of a substrate a photosensitive resin film comprising (i) a substrate film and (ii) a pressure-sensitive adhesive, photosensitive resin layer provided on one side of the substrate film, said photosensitive resin layer including a photosensitive resin that contains a fluorescent substance and, upon exposure, causes the tackiness of exposed areas to be lowered;pattern-wise exposing the photosensitive resin film;separating and removing the photosensitive resin film from the surface of the substrate so that only exposed areas of the photosensitive resin layer remain on the surface of the substrate; andfiring the photosensitive resin layer formed on the substrate to obtain a fluorescent substrate pattern for a fluorescent display device,said method including no developing step by means of a wet process.
