The present disclosure relates to a display device for improving productivity. The display device having a touch sensor is configured such that the total thickness of at least one inorganic insulation layer disposed on the region above each of dams is different from the total thickness of the at least one inorganic insulation layer disposed on a trench region between the dams. Thus, a photoresist for forming a routing line is formed so as to have a uniform thickness on the region above each of the dams and the trench region between the dams, and thus productivity is improved.

A touch display device for preventing deterioration in image quality is structured such that a plurality of touch sensors is disposed on an encapsulation unit encapsulating a light-emitting element and includes a driving signal line, which includes a first driving signal line disposed below the encapsulation unit and a second driving signal line disposed above the encapsulation unit so as to be in contact with the first driving signal line to reduce line resistance of the driving signal line, thereby preventing deterioration in image quality.
