Summary:Devices and methods for forming a spatial light modulator with high contrast are described. Light absorbing materials are used within a chamber that houses a spatial light modulator. The light absorbing materials absorb reflected light that is not intended for forming a part of a display image. The light absorbing material can form an aperture layer, wherein light to form the display image is transmitted through an opening in the aperture layer. An array of spatial light modulators can be within the housing and dummy spatial light modulators may be formed to enable easy alignment of the array with the opening in the aperture layer.
