Abstract: A display device includes: a display panel having a display region in which pixels are arranged; scan lines each coupled to the pixels arranged in a row direction; signal lines each coupled to the pixels arranged in a column direction; a signal line drive circuit; a scan line drive circuit selecting the scan lines; and a signal processing circuit. A second half period of a selection period of a first scan line overlaps a first half period of a selection period of a second scan line. The signal processing circuit adjusts a pixel gradation value of the pixel in an m-th column coupled to the second scan line when a difference value between the pixel gradation value of the pixel in the m-th column coupled to the first scan line and an average gradation value of the pixels arranged in the m-th column is larger than a predetermined value.
