Touch screen panel and fabrication method thereof

A fabrication method for a touch screen panel comprising first sensing patterns that are arranged in a first direction and include first sensing cells and first connection parts and second sensing patterns that are arranged in a second direction and include second sensing cells and second connection parts, a transparent substrate that incorporates a display region and a non-display region formed at the outside of the display region and an insulation layer, the method comprising:

• forming the second connection parts arranged in the second direction on the display region of the transparent substrate;
• forming an insulating layer comprising spatially separated first insulating portions on the second connection parts, each first insulating portion having an island shape to expose ends of the second connection parts;
• forming the second sensing cells that are arranged in the second direction and contact the exposed ends of the second connection parts to be electrically connected to each other;
• arranging the first sensing cells on the display region in the first direction to intersect with the second direction;
• and further comprising
• forming a pair of auxiliary patterns that are positioned under the insulating layer and are spaced by an interval from a corresponding side of the second connection parts,
• wherein the first connection parts that connect adjacent first sensing cells to each other are formed on the insulating layer, the auxiliary patterns are electrically connected to corresponding ones of the first sensing cells, and at least a portion of the insulating layer is interposed between the pair of auxiliary patterns.
