Abstract: According to an aspect, a display device with a touch detection function performs image display and touch detection in a time division manner in one frame period. The display device includes: a plurality of pixel electrodes arranged in a matrix in a display region in which an image is displayed; a display function layer having an image display function for displaying an image in the display region; a plurality of touch detection electrodes opposed to the pixel electrodes; and a detection unit that performs noise detection. The one frame period includes a plurality of display operation periods for displaying the image and a plurality of detection operation periods for performing at least touch detection. The detection unit performs the noise detection in a period that is included in the detection operation period and shorter than one of the detection operation periods in the one frame period.
