Abstract
A method of forming a fluorescent screen for a plasma display panel provided with a front plate and a rear plate disposed parallel to each other and a cell barrier mounted on the front or rear plate and constituting a plurality of cells as display elements is characterized in that the cell barrier is located on a surface of the front or rear plate facing the other plate, a slurry solution containing a phosphor is filled in a portion defined by a cell wall of the cell barrier on the front or rear plate, only the wall surface of the cell barrier is exposed, and so a photosensitive layer containing a phosphor is formed at a portion inside the cell barrier. The fluorescent screen forming method is further characterized in another aspect in that a slurry solution containing a phosphor fills inside the cell of the cell barrier disposed on the plate, the plate is inclined immediately thereafter with an inclination of about 90.degree. or more degrees with respect to a horizontal plane, the rear plate in an inclining state is settled till the phosphor in the slurry solution is precipitated on the cell wall of the cell barrier, and the cell wall after the precipitating process is dried and h…
