Claim 13:
14. An edge-lit dual side view display comprising:
a waveguide comprising an inside transparent layer and an outside transparent layer spaced apart from and parallel to the inside transparent layer;
a light source attached to an edge of the waveguide and coupled into the edge-lit dual side view display;
a plurality of inside view liquid crystal (LC) pixels disposed within the waveguide and comprising a plurality of outside blocking layers configured to block light scattered in the plurality of inside view LC pixels from propagating through the outside transparent layer, the plurality of outside blocking layers selected from the group consisting of a plurality of black absorbing layers and a plurality of reflecting layers; and
a plurality of outside view LC pixels disposed within the waveguide parallel to and in-plane with the plurality of inside view LC pixels, the plurality of outside view LC pixels comprising an inside electrode, and a plurality of inside blocking layers sandwiched between and in direct contact with the inside electrode and the inside transparent layer and configured to block light scattered in the plurality of outside view LC pixels from propagating through the inside transparent layer.
