Abstract: A wire grid polarizer plate includes a transparent substrate, metal partition walls and metal oxide partition walls. The metal partition walls are disposed on the transparent substrate and spaced apart from one another. The metal partition walls includes at least one metal selected from aluminum (Al), titan (Ti), molybdenum (Mo), chrome (Cr), silver (Ag), copper (Cu), nickel (Ni) and cobalt (Co). The metal oxide partition walls are disposed on the metal partition walls. The metal oxide partition walls includes an oxide of the at least one metal. An average of surface roughness of the wire grid polarizer plate is about 4 nm or less when a thickness of the metal oxide partition walls is equal to about 300 Å.
