    Abstract: A touch display device and a touchscreen panel. Even in the case in which touch electrodes have different sizes or shapes or a located in different positions, a difference in capacitance is not formed among the touch electrodes. High touch sensitivity can be obtained. The touch display device comprises a plurality of touch electrodes, wherein a first touch electrode of the plurality of touch electrodes occupies a first area and comprises first mesh-shaped electrode metal. The touch display device comprises first dummy metal in a same layer as the first mesh-shaped electrode metal and in the first area occupied by the first touch electrode, the first dummy metal being electrically disconnected from the first mesh-shaped electrode metal.
