Abstract
A liquid crystal panel shading system is disclosed in which the light transmission characteristics of a liquid crystal panel are varied to produce desired shading effects. The preferred embodiment is disclosed in the application to a windshield sun visor for an automotive vehicle. The panel may be a separate element applied against the existing windshield or it may be integrally incorporated into the windshield. The panel is constructed with a tapered shape, which in association with a control, is effective to produce zones of varying light transmission characteristics to produce new and unique modes of shading.
