1. A method of fabricating a touchscreen panel, comprising:

  • forming a first substrate having a first transparent conductor layer provided on a first base layer;

    forming a second substrate having a second transparent conductor layer provided on a second base layer;

    segmenting the first transparent conductor layer into an array of M rows by N columns of conductive regions that are electrically insulated from each other, where M and N are natural numbers greater than or equal to 2; and

    bonding the first and second transparent conductor layers with a spacer interposed therebetween so that the first and second transparent conductor layers oppose each other and make contact when the first base layer is pressed,wherein said segmenting the first transparent conductor layer is performed before said bonding the first and second transparent conductor layers, andwherein one column of the conductive regions is formed to includea first conductive region coupled to a first electrode at one end of the first substrate extending in a direction along the rows, anda second conductive region, having a leader part extending along and between one side of the first conductive region and a column adjacent to the one column, and coupled to a second electrode via the leader part at the one end of the first substrate.
