Abstract
A liquid crystal projection panel for use in a projection system. The projection panel is comprised of a large number of pixels of liquid crystal defining a image forming plane provided between two transparent substrates. Microlens arrays are provided on both sides of the projection panel. The microlenses in both arrays have focal lengths such that parallel light rays entering the microlenses at an angle perpendicular to the arrays are focused at points beyond the image forming plane of the display.
