<p>PROBLEM TO BE SOLVED: To provide a uniform electron emission characteristic by generating a forming voltage that rises with time while its rate of rise decreases, and performing a forming process while providing a connection so that the voltage can be applied to a plurality of electron emitting elements. SOLUTION: A forming voltage source 2 produces a voltage which increases in amplitude with time while the rate of increase of the amplitude decreases with time. The voltage source 2 is connected to the row wiring of an M×N electron-emission-element simple matrix 1001 via a switching-element array 3, and the forming voltage is applied to the surface conduction type emitting elements to form electron emitting parts. Since the rate of rise of the forming voltage decreases with time, even if the elements at a row end are given high resistance, fluctuation of the applied voltage can be reduced, so that uniform forming can be achieved throughout the row of elements.</p> |
