According to the present invention, a rearview mirror comprises a first substrate (12) having a front surface (12a) and a rear surface (12b), a reflective coating (15) disposed on a surface of the first substrate (12), and an electronic circuit component (24) secured to the rear surface (12b) of the first substrate (12). The mirror element may be an electrochromic mirror element comprising a transparent second substrate positioned in front of the first substrate. The electronic component secured to the rear surface may be a component of a drive circuit for the electrochromic mirror element. The rearview mirror element may further comprise electrically conductive tracings (150a, 150b) provided on the rear surface of the first substrate electrically coupled to the electrical component. The tracings (150a, 150b) is used to electrically couple the drive circuit to the electrodes of the electrochromic mirror element. The tracings is deposited on the rear surface using numerous methods including inkjet printing techniques.
