DISPLAY DEVICE HAVING INPUT SENSOR AND FABRICATING METHOD OF THE INPUT SENSOR

An input sensor of a display device includes: a sensing electrode on a base insulating layer and overlapping a sensing region; and a signal line electrically connected to the sensing electrode and overlapping the non-sensing region, and including: a first conductive layer on the base insulating layer and having a first reflectance, a first conductivity, and a first thickness; a second conductive layer having a second reflectance lower than the first reflectance, a second conductivity lower than the first conductivity, and a second thickness smaller than the first thickness, wherein the second conductive layer is on and in contact with the first conductive layer; and a third conductive layer between the base insulating layer and the first conductive layer, in contact with each of the base insulating layer and the first conductive layer, wherein the third conductive layer contains a material different from that of the second conductive layer.
