This display device comprises a display panel whereon a plurality of pixels are disposed, and a drive unit for driving the display panel. The display device includes: a conversion unit that convers an original signal representing the luminance of the pixel into a brightened signal and/or a darkened signal; a calculation unit that calculates the difference in luminance of the original signal between one pixel unit and another pixel unit located next to the one pixel unit; a determination unit that determines whether or not the difference in luminance exceeds a threshold; a selection unit that selects the original signal when determined that the difference in luminance exceeds the threshold, and selects the brightened signal or the darkened signal when determined that the difference in luminance does not exceed the threshold; and an input unit that inputs an input signal based on the signal selected by the selection unit into the drive unit.
