An electro-optic device including first and second optically transparent elements mounted in spaced relationship to each other to define a gap and each having a front and rear surface. At least one optically transparent interlayer element is sandwiched between the first and second elements and joining a predetermined area of the rear surface of the first element and the front surface of the second element. A liquid, semi-liquid, gel, or semi-solid electro-optic medium, whose light transmittance is variable, is added to the gap between the first and second element. One surface of the second element may include a reflective coating except in those areas aligned with the transparent interlayer element sandwiched between the first and second element. A photoelectric cell/sensor or display is disposed behind the rear surface of the second element and may be aligned with the window formed in the reflective coating so as to receive or transmit light through the first element, the transparent interlayer, and the transparent second element.
