Abstract: A wire grid polarizer may be fabricated by forming plurality of substantially-straight metallic lines of predetermined periodicity ? on a thin film substrate A plurality of substantially straight nanometer-scale periodic surface relief structures is created on a surface of the substrate. The periodic surface relief structures cover a region greater than about 4 centimeters in length and greater than about 4 centimeters in width, wherein the periodicity ? is between about 10 nanometers and about 500 nanometers. One or more layers of material are formed on the periodic relief structures. The one or more layers include one or more conductor materials that form the plurality of substantially straight metallic lines over a region of the substrate greater than about 4 centimeters in length and greater than about 4 centimeters in width.

Abstract: A direct view display apparatus is disclosed. The direct view display apparatus comprises a source of backlight, a liquid crystal array; a tandem reflective polarizer having two or more reflective polarizer elements disposed in tandem between the source of backlight and the liquid crystal array; and a second polarizer. The liquid crystal array is disposed between the tandem reflective polarizers and the second polarizer. The second polarizer is an absorptive polarizer.

Abstract: A method for forming a plurality of parallel metal lines on a substrate of thin film elastomeric material and a wire grid polarizer formed by such method. A sacrificial layer is formed by coating the substrate with a water soluble polymer while the substrate is stretched. The existing tensile force is removed, leaving an undulating topology of buckled sacrificial layer material. A masking layer is then deposited at an oblique angle and then fractured into parallel lines of material by application of a second tensile force. Unmasked portions of the sacrificial layer are removed by dry etch. A metallic layer is then deposited and a lift off process employed to remove remaining portions of the sacrificial layer and materials deposited thereover. Upon removal of the second tensile force, the substrate returns to its unstressed length with metal lines of predetermined periodicity thereon.
