Abstract
An image display apparatus comprising: a plurality of pixels each having an electron emitting element and a light emitting area to be irradiated by electrons from the element; and a driving circuit for outputting a driving signal that drives the element, wherein the plurality of the light emitting areas include a plurality of light emitting areas that respectively emit light emitting colors differing from each other, wherein the circuit includes a correction circuit for correcting an input signal, and wherein the correction circuit executes a correction to the input signal for a predetermined electron emitting element based on a value obtained by adjusting a value corresponding to a quantity of electrons emitted from an electron emitting element proximate to the predetermined electron emitting element by a value corresponding to the light emitting color of the light emitting area of the pixel to which the proximate electron emitting element belongs.
