Abstract:
1. A touch panel, comprising: a substrate having an active area and a dead area; a plurality of first sensors in the active area of the substrate, each including a first series of a plurality of first electrodes serially connected by a plurality of first connection patterns, and a second series of a plurality of first electrodes serially connected by a plurality of first connection patterns, wherein the first and second series are parallel; a plurality of second sensors in the active area of the substrate, each including a third series of a plurality of second electrodes serially connected by a plurality of second connection patterns, and a fourth series of a plurality of second electrodes serially connected by a plurality of second connection patterns, wherein the first sensors and the second sensors are crossing each other, wherein the third and fourth series are parallel; a plurality of first redundancy patterns connecting the first series to the second series between the first series and the second series; a plurality of second redundancy patterns connecting the third series to the fourth series between the third series and the fourth series, at least one dummy pattern disposed between at least one of the plurality of first electrodes and at least one of the plurality of second electrodes that are adjacent to each other, wherein the first electrodes of the first series are connected to the second electrodes of the second series by the first redundancy patterns to prevent line failure through a bypass between the first series and the second series in each of the first sensors in the active area, and wherein the second electrodes of the third series are connected to the second electrodes of the fourth series by the second redundancy patterns between the third series and the fourth series in each of the second sensors in the active area; a plurality of first routing lines in the dead area of the substrate, wherein each of the first routing lines is electrically connected to only ends of the first series of the first electrodes and the second series of the first electrodes in each first sensor by a first connection part; and a plurality of second routing lines in the dead area of the substrate, wherein each of the second routing lines is electrically connected to only ends of the third series of the second electrodes and the fourth series of the second electrodes in each second sensor by a second connection part, wherein the first and second routing lines and the second connection pattern are directly on a first layer of the substrate in a same layer and include at least one metal selected from molybdenum (Mo), copper (Cu), silver (Ag), chromium (Cr), aluminum (Al), aluminum neodymium (AlNd) and molybdenum titanium (MoTi), or a laminate including the at least one metal, wherein the first and second series of the first electrodes, the third and fourth series of the second electrodes, the first connection pattern, the at least one first redundancy pattern and the at least one second redundancy pattern are on a second layer of the substrate in a same layer, and wherein the first connection patterns and the second connection patterns cross over each other, and the first redundancy patterns and the second redundancy patterns do not cross over each other.
