Abstract:
An image display apparatus includes a display panel having a plurality of electron emission portions that emit electrons, a plurality of light emitting regions positioned corresponding to the plurality of electron emission portions to emit light in response to irradiation of electrons from the electron emission portion thereon, and a shielding member provided between a substrate having the electron emission portions provided thereon and an opposing substrate having the light emitting regions thereon, and a correction circuit that corrects a pixel signal for modulating the electron emission portions. The shielding member shields electrons reflected from peripheral light emitting regions adjacent to a predetermined one of the light emitting regions to the predetermined light emitting region, and irradiates electrons from the shielding member to the predetermined light emitting region. The correction circuit carries out correction of the pixel signal with a correction value corresponding to the amount of electrons shielded by the shielding member among electrons to be irradiated to the light emitting region and correction with a correction value in which the amount of electrons irradiated from the shielding member to the light emitting region.
