1. A display filter, comprising:

  • a base substrate;

    a conductive film coating layer formed on the base substrate;

    a touch sheet, wherein the touch sheet and the conductive film coating layer are arranged with an air gap therebetween such that the touch sheet is brought into contact with the conductive film coating layer in response to a touch pressure applied from outside;

    a first electrode formed on a surface of the touch sheet that faces the conductive film coating layer, wherein the first electrode includes a first electrode part to which a first input voltage is applied to generate potential distribution in an x direction and a second electrode part to which a second input voltage is applied to generate potential distribution in a y direction; and

    a second electrode formed on a peripheral portion of the conductive film coating layer, wherein the second electrode allows electrical current to flow through when the touch sheet is brought into contact with the conductive film coating layer,whereby information input is enabled by touching of the touch sheet.
