Abstract: 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.
