Claim:
1. A complex substrate for a display apparatus, the complex substrate comprising: a lower base substrate including convex and concave patterns, the convex and concave patterns defining a light condensing layer on the lower base substrate, and the light condensing layer being integral with an upper side of the lower base substrate; a planarizing layer on the lower base substrate, the planarizing layer being integral with the convex and concave patterns, and the planarizing layer having different refractivity from the lower base substrate; and a wire grid pattern directly on the planarizing layer, the planarizing layer being between the wire grid pattern and the light condensing layer, and the wire grid pattern including a plurality of nano wire metal patterns, each of the nano wire metal patterns having a width of no more than a micrometer, wherein the lower base substrate, the convex and concave patterns, and the planarizing layer are integrated into a single structure having flat upper and lower surfaces, and wherein the planarizing layer has a complementary shape with respect to the convex and concave patterns, the planarizing layer fitting within spaces between adjacent convex and concave patterns, and lateral outermost surfaces of the planarizing layer being coplanar with respective lateral outermost surfaces of the lower base substrate.
