Abstract
An image display apparatus according to the present invention comprises a plurality of electron emitting devices having an electron emitting portion provided between a cathode electrode and a gate electrode; a cathode wiring connected to the cathode electrode; and a gate wiring connected to the gate electrode and having a resistance higher than the resistance of the cathode wiring, wherein an impedance element having a resistance value of Ry and an electrostatic capacitance of Cy is connected to between the cathode wiring and the cathode electrode, a resistive element having a resistance value of Rx is connected to between the gate wiring and the gate electrode, and |Ry/(1+jωRyCy)|<Rx and Ry>Rx are satisfied, where ω is 100 MHz.
