A polarizing cube includes a pair of identical and symmetric triangular prisms which sandwich a thin optical composite plate containing a planner array of reflective straight wires spaced apart in parallel as a built-in wire grid polarizer. All of its subcomponents and the polarizing cube itself are physically and optically symmetrical to one of its diagonal planes so as to provide improved integration and robustness for projection display application. The cubic configuration of the disclosed polarizer can be readily produced through common means and sequences typically used in semiconductor wafer fabrication processes, including photolithographic patterning, gap dielectric filling and planarization, and wafer thinning, bonding and cutting among others.
