PROBLEM TO BE SOLVED: To suppress motion blurring which occurs at the time of moving image display in a hold type image display apparatus while suppressing deterioration of the maximum luminance and contrast. SOLUTION: In the image display apparatus in which image display of one frame period is constituted by a plurality of sub-frame periods, a gradation level of an image signal in each sub-frame is set so that relation between an inputted image signal and display luminance shows appropriate gamma luminance characteristics while suppressing an event that a time-wise center position of the display luminance moves in accordance with the gradation level of the inputted image signal. For example, the maximum gradation level is sequentially supplied from a time-wise center of n (n is an integer≥2) sub-frame periods or a sub-frame period closest to the center to horizontally adjacent sub-frame periods within a range that it does not exceed a target luminance level and at the time when the target luminance level is reached, the minimum gradation level is supplied to the remaining sub-frame period.
