Abstract

A cube wire-grid polarizing beam splitter (10, 10b) includes a pair of prisms (18, 22) secured together to form a cube. An array (30) of parallel conductive wires (34) is disposed between the pair of prisms. A pair of continuous film layers (42) is disposed on one side of the wires between the wires and one of the pair of prisms with an intermediate film layer (46, 46b) adjacent the prism having a refractive index greater than both i) a refractive index of a rear film layer (50, 50b) adjacent the plate wire grid polarizer, and ii) a refractive index of an adjacent prism. A layer of ribs (62) is disposed on another side of the wires between the wires and another of the pair of prisms, the ribs being aligned with and supporting the array of parallel conductive wires. A display apparatus (100) includes a cube wire-grid polarizing beam splitter.
