ABSTRACT:
To provide an image display apparatus having: an electron source; a light-emitting member for emitting a light by irradiation with electrons emitted from the electron source; an anode electrode, which is arranged being opposed to the electron source; a high-voltage generating circuit for generating a potential which rises in a predetermined period; a wiring for connecting the anode electrode to the high-voltage generating circuit; a comparator; a first circuit for applying a first potential satisfying a positive correlation with the potential on the wiring to the comparator; and a second circuit for applying a second potential, which continuously rises or rises in stepwise manner in the predetermined period, to the comparator. The comparator outputs a result of comparison between the first potential and the second potential.
