Abstract
This invention relates to display apparatuses having an array of light modulators for transmissively displaying an image and a reflective aperture layer defining a plurality of apertures, for reflecting light not passing through apertures in the reflective aperture layer away from the array. The reflective aperture layer is formed on a first substrate and positioned adjacent the array. The image is formed by modulating light passing through the apertures in the reflective aperture layer. A light guide, separated from the first substrate by a gap, may guide light towards the reflective aperture layer. A layer of low-refractive index material may be positioned on a side of the reflective aperture layer opposite the array.
