PURPOSE:To obtain fluorescent layers of uniform shapes with minimum sticking out of an electrodes, by placing a substrate inclined downward in an electrodeposition liquid to perform electrodeposition, and after stopping agitation and the electrodeposition liquid has come to stand still, taking out the substrate from the electrodeposition liquid. CONSTITUTION:After fully agitating an electrodeposition liquid 1 an anode substrate 2 on which multiple anodes 7 are arranged and an opposing electrode 3 are dipped in the electrodeposition liquid while being inclined from the vertical direction. The substrate 2 is placed diagonally above the electrode 3 with the surface to be electrodeposited downward. Under this condition, while agitating the electrodeposition liquid 1, voltage is applied by means of a DC power source 4 to perform electrodeposition, with the electrode 3 positive and the substrate 2 negative. When the electrodeposition is finished, an agitator 8 is stopped and, when the electrodeposition liquid 1 has settled down, substrate 2 is taken out quietly and is dried. During this process, fluorescent particles other than those deposited on the anode 7 drop due to the gravity, and disfigurement of the fluorescent layer deposited on the anode 7 is prevented because the electrodeposition liquid 1 is made to stand still when the substrate 2 is take out. thus fluorescent layers of uniform shapes with minimized sticking out of the electrodes can be formed without contact of adjacent fluorescent layers.
