A display device which displays a multilevel gradation image by dividing a frame into a plurality of subfields in respect of time and by allowing the subfields corresponding to the luminance levels of the input image signals to emit light, comprising a motion vector detection unit 10 which detects the motion vector which expresses the motion of a block from one frame to the next, a high speed dynamic image correction unit 14 and a law speed dynamic image correction unit 16 which correct the input image signal by dynamic image correcting means which are suitable for the respective cases when the value of the detected motion vector is larger than a preset value S and when it is smaller than the preset value S and output the corrected input image signal, and a switching unit 18 which elects either the output signal of the high speed dynamic image correction unit 14 or the output signal of the law speed dynamic image correction unit 16 to output the selected signal to the display in accordance with whether or not the value of the detected motion vector is larger than the preset value S. As a result, both the high speed dynamic image part and the low speed dynamic image part of the image can be optimally corrected.
