An image display apparatus includes: a region division unit that divides a display surface into a plurality of regions; a degree-of-influence calculation unit that calculates a first degree of influence representing a degree of influence of a brightness level of each of the regions on a brightness level of a respective region adjacent to the region; and a brightness correction unit that corrects a brightness level of each pixel. Influence of not only a location of connection in wiring in a display unit with an input terminal of a power supply for the display unit but also a wiring configuration of the display unit is reflected on the first degree of influence.
