Abstract
A multi-layer flat panel display screen. The present invention includes a multi-layer flat panel display screen including a rear polarizer for polarizing incident light; a back glass structure disposed adjacent to the rear polarizer; a thin film matrix for selectively polarizing light emitted through the rear polarizer, the thin film matrix including a transistor layer having a two-dimensional matrix of individually addressable transistors; a color filter layer; and a liquid crystal layer disposed between the transistor layer and the color filter layer. The multi-layer flat panel display screen also includes a front glass structure disposed adjacent to the thin film matrix; a front polarizer for polarizing light emitted through the thin film matrix; and an anti-reflective and conductive layer for increasing light intensity and for reducing electromagnetic emissions, the anti-reflective and conductive layer composed of alternating layers of a dielectric layer and a transparent conductive layer, wherein the transparent conductive layers are grounded wherein the anti-reflective and conductive layer is disposed on the front polarizer.
