Abstract: Disclosed are an apparatus and method for manufacturing a flat display panel. In forming sustain electrodes and address electrodes, to which electricity is supplied to discharge, on front and rear panels, electrode material, which resides in electrode forming grooves formed on the surface of an electrode roll and each having the same shape as that of electrodes, is transferred on a substrate. The electrode roll transfers the electrode material to the substrate while coming into close contact with and rotating on the substrate. The electrode material adhering to the surface of the electrode roll using a cleaner before the electrode roll transfers the electrode material to the substrate.
