An image display apparatus, which displays an image in multiple grayscales on a display panel by combining a plurality of weighted subfields into which one field has been divided, has an SF usage rate detection circuit, a display SF selection circuit, an SF conversion circuit, and a driving control circuit. The SF conversion circuit selects one of a plurality of prestored light emission pattern tables and outputs an encoded subfield data by encoding an input image signal in accordance with a selected light emission pattern table. The driving control circuit receives an output of the SF conversion circuit, and drives the display panel in accordance with a prescribed driving sequence.
