According to an aspect, a display device with a touch detection function includes: a touch detection electrode that detects proximity or contact of an object; a drive electrode to which the excitation signal is applied; a first substrate on which the drive elements are provided; a second substrate on which at least one of the touch detection electrode and the drive electrode is provided, the second substrate being bonded to the first substrate to face each other via a sealing member; a conductor that electrically is coupled to at least one of the touch detection electrode and the drive electrode; and a conductor support member that fills a space between the first substrate and the second substrate and on the surface of which the conductor is provided.
