Single-layer and multi-layer light filters each having an array of light transmissive beads provide substantially independent and simultaneously optimized control of optical properties such as gain, contrast, transmittance, dispersion, and ambient light rejection using additional light transmissive layers. Such light filters can include light transmissive layers defining a lens curved over a plurality of the beads for effecting greater dispersion of image light horizontally or vertically, and conformal layers defining a lens curved over individual beads for increasing an effective radius of curvature of such beads. Additional pluralities of smaller beads are included in interstitial gaps in an array of larger beads for improving transmittance of some embodiments of light filters of the present invention. Light filters of the present invention are beneficially used as rear projection screens and light diffusers, and are ideal for use in or with flat-panel displays and the like.
