Abstract
An image display apparatus includes a light-source driving circuit that drives a light source to cyclically change brightness. A control unit controls a pixel to turn on and off over a plurality of subfields in a field so that transmittance or reflectance in the pixel over the plurality of subfields in the field corresponds to a gray level specified for the pixel. The control unit also arranges the plurality of subfields such that two or more gray-level defining subfields maintain a predetermined relationship with respect to the cyclical change in brightness of the light source caused by drive of a light-source driving circuit.
