The photosensitive resin which exhibits stickiness by photo-reaction is added with a binder which does not substantially raise dark reaction, and a resultant mixture is applied onto the inner surface of face panel of the color picture tube to form a film. Portion of the film where powdery material is going to be applied is exposed to light and rendered sticky. Phosphor powder, when used as the powdery material, is applied to the sticky portion and adhered thereto to form a fluorescent screen.
