ABSTRACT:
A transmissive, backlit color twisted-nematic or super-twisted-nematic liquid crystal display employing a front fiber-optic faceplate or optical equivalent as a front retaining element of a liquid crystal cell that increases viewing angle between the display and a viewer while minimizing or eliminating undesirable variations in luminance, contrast ratio and chromaticity is described. In particular, the fiber-optic faceplate or optical equivalent includes cylindrical optical features and interstitial cladding material. The interstitial cladding material may include an opaque mask blocking layer to prevent the interstitial apertures from diffracting off-axis light into an observer's viewing cone. Further, the interstitial cladding material may be opaque.
