In various embodiments of the invention, an interferometric light modulating display device is provided having a touchscreen above the light modulating display device. The touchscreen may have a diffusing material that may be part of the touchscreen. In some embodiments, the diffusing material may be used to reduce or minimize the color-shift or may be used to change the properties of light reflected by the display such that light modulating display device appears more diffuse and less specularly reflecting. In other embodiments, a light source is provided beneath the touchscreen and one or more reflective surfaces are provided such that at least a portion of the light from the light source that is directed toward the touchscreen is reflected to the light modulating device without passing through the touchscreen. In other embodiments, a diffusing material is provided that may scatter light using different sized scatterers.
