Abstract: A touch sensor includes a sensing pattern including a first pattern and has unit patterns connected with each other through connection parts thereof, and a second pattern having separated unit patterns, and bridge electrodes connecting the separated unit patterns, wherein at least a portion of a boundary between the first pattern and the second pattern includes convex parts of a curved line and concave parts of a curved line between the convex parts, and the convex part of the first pattern and the concave part of the second pattern face each other, and the concave part of the first pattern and the convex part of the second pattern face each other. The touch sensor has excellent touch sensitivity while suppressing an occurrence of cracks in the sensing pattern due to a stress concentration during bending, and preventing the sensing pattern from being viewed by a user.
