PROBLEM TO BE SOLVED: To provide a technology for implementing a decrease of the processing band of storage unit, which is required for reading correction data used for processing to decrease gradation-dependent brightness variation from the storage unit, without dropping brightness variation correction performance. SOLUTION: An image display apparatus includes: a display panel; a storage means for storing a plurality of correction values which are used for correction processing for decreasing brightness variation; a correction means; and a control means, wherein the control means divides the display panel into a plurality of sub-areas, calculates, for each sub-area, a select block gradation value, and executes, for each sub-area, a control to read correction values, which are used for calculating a correction value corresponding to the select block gradation value, out of the plurality of correction values, using the correction means, and the correction means calculates, for each sub-area, a correction value corresponding to the select block gradation value using the read correction values, and converts gradation values of video signals in the sub-area using the calculated correction value.
