Abstract: The present embodiments generally relate to a display panel and a display device which may recognize touch. A display panel is provided in which a touch sensor and a touch line are disposed in an active area in which a part of an outer edge of the touch line is curved to correspond to a curved shape of the active area in the display panel so that the touch sensing is allowed in display panels having various shapes. Further, a touch display device is provided in which an open area is located between two adjacent touch lines disposed on the display panel so that touch sensing is allowed also in the display panel including an open area such as a hole or a notch.

Abstract: Embodiments of the present disclosure relate to a touch panel and a touch display panel, wherein touch electrodes including bodies and wings are arranged so as to interlock with each other to thus reduce a difference in sensing sensitivity depending on position and a movement direction, thereby improving uniformity of touch sensing. In addition, the body and wing of the touch electrode can be arranged so as to be varied in length/width depending on the position thereof, so that the boundary area between the touch electrodes is increased, thereby improving the intensity of a touch-sensing signal, and so that sensing time is reduced, thereby enhancing the performance of touch sensing.

Abstract: A touch display device and a touchscreen panel. Even in the case in which touch electro des 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 displ ay device comprises a plurality of touch electrodes, wherein a first touch electrode of the pluralit y 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 electr ode 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.
