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 display device includes a display panel and a signal transmission film including a first extension portion, a second extension portion, and a first dummy pattern. The signal transmission film is connected to one side of the display panel. The first extension portion extends in a first direction, and a first contact hole is formed at a first side of the first extension portion. The second extension portion extends from the first side of the first extension portion in a second direction which is different from the first direction. The first dummy pattern is disposed adjacent to the first contact hole at the first side.

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.
