Abstract
In a liquid crystal display system constructed from a plurality of liquid crystal display cells stacked one on top of another, a light guide adapted to transmit light only in a direction perpendicular to the display surfaces of the liquid crystal display cells is interposed between the first liquid crystal display cell disposed nearest to an observer and the second liquid crystal display cell disposed behind the first liquid crystal display cell. Because of the provision of the light guide, the images formed on the second and third liquid crystal display cells are focused through the light guide onto the rear surface of the first liquid crystal display cell, viewed from the direction of the observer. The light guide is a sheet of optical fibers or a stack of sheet like members separated by refletion films, the plane of which are perpendicular to the plane of the display.
