1. A display device with a touch detection function comprising:

  • a variable focus lens unit that includesa first substrate including a first electrode,a second substrate including a second electrode, anda variable focus layer that is provided between the first electrode side of the first substrate and the second electrode side of the second substrate and in which a refractive index of transmitted light varies depending on a certain signal applied between the first electrode and the second electrode;

    a display unit including a display region that displays an image via the variable focus lens unit;

    a drive electrode that is arranged in the display unit or at a position opposed to the display region, and divided into a plurality of pieces; and

    a touch detection unit configured to detect a position of a proximity object using one of the first electrode and the second electrode as a touch detection electrode based on change in capacitance with respect to the drive electrode.
