Abstract: An image data correcting device included in a display device includes a correction data memory and a correction calculator. The correction data memory stores sampling window select information indicating a sampling window selected from a plurality of sampling windows that are different from each other, and correction data obtained utilizing the selected sampling window with respect to the display device. The correction calculator receives image data, and corrects the image data based on the correction data for pixels at positions corresponding to the selected sampling window indicated by the sampling window select information.
