A light transmitting conductive film formed by patterning a conductive metal part and a visible light transmitting part on a transparent support, wherein the conductive metal part is made up of mesh-forming thin lines of from 1 µm to 40 µm in size and the mesh pattern continues for 3 m or longer. A method of producing a display filter wherein the end sections of at least two sides facing each other are in a mesh shape, which comprises using an electromagnetic wave shielding material (C), wherein a conductive layer (B) having the conductive parts being in the mesh shape of the geometric pattern is formed on one face of a polymer film (A) continuously in the machine direction of the polymer film (A), and cutting the mesh-like parts.
