An image display apparatus includes: a display panel including an image display area and a dummy pixel area different from the image display area; an optical sensor detecting light emission luminance of the dummy pixel area on the display panel; and a control unit dividing the image display area on the display panel into a plurality of division areas, allowing pixels within the dummy pixel area to perform light emission to the same degree as the light emission of one or a plurality of pixels within each division area, and correcting luminance or chromaticity of the pixels within each division area based on the light emission luminance of the dummy pixel area detected by the optical sensor.
