Abstract: Wire grid polarizer and manufacturing method thereof are provided, the wire grid polarizer includes: substrate; first wire grid formed on substrate, including first wire grid reflection strips arranged parallel to each other and at equal intervals; second wire grid formed at a side of first wire grid away from substrate, including second wire grid reflection strips arranged in parallel to each other and at equal intervals; second wire grid reflection strips are in one-to-one correspondence with first wire grid reflection strips; orthographic projections of second wire grid reflection strip onto substrate falls within orthographic projections of corresponding first wire grid reflection strip onto substrate; wire width of second wire grid reflection strip is less than that of first wire grid reflection strip; and wire spacing of second wire grid reflection strip is greater than that of the first wire grid reflection strip.
