A spatial light modulator includes an array of elements to modulate light in accordance with image data. The modulator has a display panel having first and second surfaces arranged adjacent to the array of elements such that the second surface is directly adjacent the array of elements to allow a viewer to view an image produced by modulation of light. The modulator may also include a light source to provide light to the display panel and illumination dots on the first surface of the display panel to reflect light from the source to the array of elements.
