Abstract:
1. A touch screen panel comprising: a plurality of first wiring lines; a plurality of second wiring lines; a plurality of separate sensing electrodes, each connected to a unique one of the plurality of first wiring lines; and a plurality of separate driving electrodes connected to the plurality of second wiring lines, in a same layer as the plurality of sensing electrodes; a board having high transmissivity on or adhered to the plurality of first wiring lines, the plurality of second wiring lines, the plurality of separate sensing electrodes, and the plurality of separate driving electrodes; wherein each of the sensing electrodes comprises a main electrode and a plurality of expanded parts, each of the expanded parts comprises a sub-electrode expanding or extending from the main electrode at a first angle of 90° or less, at least one expanded electrode expanding or extending from an end of the sub-electrode in a first direction at a second angle of 90° or less and in a second direction at said second angle, said second direction being different from said first direction and said expanded electrode having one end along said first direction and another end along said second direction, a first auxiliary expanded electrode expanding or extending from said one end of the expanded electrode, and a second auxiliary expanded electrode expanding or extending from the other end of the expanded electrode in a direction different from the at least one expanded electrode, lengths of the first and second auxiliary expanded electrodes increase as a distance from the plurality of first wiring lines increases, and each of the driving electrodes surrounds at least part of a corresponding one of the expanded parts.
