Claim:
1. An ultraviolet (UV) polarized light splitting element, comprising: a substrate; and an unevenness having a convex part including a light absorbing material having a refractive index of 3.2 to 10 and an extinction coefficient of 0.5 to 10 with respect to light having a wavelength of 300 nm, and a concave part including a dielectric material, the unevenness being formed on the substrate, wherein the convex part has a pitch of 100 to 180 nm, a width of 50 to 80 nm, and a ratio (W/P) of a width (W) of the convex part to a pitch (P) of the convex part is 0.2 to 0.8, wherein in the following Equation 1, a is 0.74 to 10, and b is 0.05 to 10, and in the following Equation 2, c is 1.3 to 10 and d is 0.013 to 0.1: where i is an imaginary number, n
