Abstract: A touch sensor includes: a first organic layer including first recesses; first conductive patterns disposed in the first recesses; a second organic layer disposed on the first organic layer, the second organic layer covering at least some of the first conductive patterns and including second recesses; second conductive patterns disposed in the second recesses; and a third organic layer disposed on the second organic layer, the third organic layer covering at least some of the second conductive patterns. Some of the first and second conductive patterns form a driving line extending in a first direction. Some of the first and second conductive patterns form a sensing line extending in a second direction crossing the first direction. The touch sensor is configured to sense a touch based on a change in capacitance between the driving line and the sensing line.

Abstract: A touch panel, a display device having the same, and a method of manufacturing the touch panel are disclosed. In one aspect, the touch panel includes a base substrate and a first sensing portion extending in a first direction and formed over the base substrate. The first sensing portion including a plurality of first fine lines defining a plurality of spaces therebetween. The touch panel also includes a second sensing portion extending in a second direction crossing the first direction and formed over the base substrate and a first insulating layer covering the first fine lines. The first insulating layer defines a plurality of openings therein corresponding to the spaces between the first fine lines. The second sensing portion crosses the first sensing portion with the first insulating layer interposed therebetween.

Abstract: A touch panel includes a substrate, a first signal line, and a second signal line. The first signal line extends on the substrate in a first direction and includes a first height from the substrate. The second signal line extends on the substrate in a second direction crossing the first direction and includes a second height from the substrate. The second signal line is disposed in the same layer as the first signal line. The second height is greater than the first height.
