A display apparatus for producing colored pixelated light includes a backlight unit for providing a pump-beam light. The apparatus also includes a microcavity light-producing array responsive to pump-beam light and having pixels wherein each pixel including a transparent substrate, a bottom dielectric stack reflective to light over a predetermined range of wavelengths, an active region responsive to pump-beam light for producing display light, and a top dielectric stack spaced from the bottom dielectric stack and reflective to light over a predetermined range of wavelengths. The apparatus further includes a light shutter for permitting selected display light from the microcavity light-producing array to pass therethrough, a polarizing layer disposed between the microcavity light-producing array and the light shutter, and a beam expander disposed over the light shutter for increasing the angular cone of view of the display light.
