Abstract: A method for fabricating a touch panel includes forming a routing and pad pattern group on a substrate to include first and second routing lines, first pad electrodes connected to the first routing line, and second pad electrodes connected to the second routing line, by using a first mask, forming a sensor electrode pattern group on the substrate having the routing and pad pattern group formed thereon to include first sensor electrodes formed in a first direction, second sensor electrodes formed in a second direction, and connection portions that each connects adjacent first sensor electrodes, by using a second mask, forming a first insulating layer to include contact holes to expose portions of the second sensor electrodes, respectively, by using a third mask and forming bridges that each connects adjacent second sensor electrodes through the contact holes and a second insulating layer on the bridges, by using a fourth mask.
