Touch detection device, and display device with touch detection function and electronic apparatus including the same

A display device with a touch detection function having a display area for displaying an image and a detection surface for detecting a position of an external proximity object which is in contact therewith or in proximity thereto, the display device with a touch detection function comprising:

• a plurality of scanning signal lines for supplying a scanning signal to the display area;
• a plurality of pixel signal lines for supplying a pixel signal to the display area;
• a drive electrode layer that has a plurality of drive electrodes each arranged at a position that overlaps with at least one of the scanning signal lines and the pixel signal lines in a direction orthogonal to the detection surface;
• a plurality of touch detection electrodes that face the drive electrodes to form capacitance between the drive electrodes and the touch detection electrodes;
• a drive electrode driver for applying a driving signal to the drive electrodes;
• and
• a plurality of wirings for electrically coupling the plurality of drive electrodes with the drive circuit, wherein
• in the drive electrode layer, among the plurality of drive electrodes, a specific drive electrode coupled via the wiring with a longest distance has an overlapped area smaller than an average of the overlapped areas of the other drive electrodes, the overlapped area being an area that is overlapped with at least one of the scanning signal lines and the pixel signal lines.
