    Abstract: A touch display device for preventing damage to test patterns is configured such that a test cover layer, which is formed of the same material as at least one of a plurality of insulating films disposed between a light-emitting element and a touch electrode, is disposed on a test pattern formed on a peripheral portion of a substrate, thereby preventing damage to the test pattern during the process of manufacturing a touch sensor.

    Abstract: Disclosed is a display device capable of being manufactured through a simplified process and having improved touch sensitivity. The display device includes an encapsulation unit disposed on a light-emitting element, a touch sensor disposed on the encapsulation unit, and an intermediate layer disposed between the encapsulation unit and the touch sensor. The intermediate layer includes a first intermediate layer, having a dielectric constant that is lower than a dielectric constant of an organic film disposed above or under the intermediate layer, and a second intermediate layer, having greater hardness than the first intermediate layer, whereby touch sensitivity is improved while processing is simplified.

    Abstract: Disclosed is a display device having a reduced non-display area. The display device includes an organic cover layer disposed on an encapsulation unit, an inner dam disposed between a substrate hole and a plurality of light-emitting elements, and a blocking element disposed between the substrate hole and the inner dam, the blocking element being disposed under the organic cover layer, whereby it is possible to prevent damage to a light-emitting stack. In addition, since the substrate hole is disposed in an active area, it is possible to reduce the size of a non-display area.

    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.

    Abstract: A display device prevents cracks from spreading to an active area. The display device includes a substrate including an active area and a non-active area having a bending area, a thin-film transistor disposed in the active area, a light-emitting element disposed in the active area and connected to the thin-film transistor, an encapsulation layer disposed on the light-emitting element, a touch sensor disposed on the encapsulation layer, a touch pad disposed in the non-active area, a first routing line connecting the touch sensor to the touch pad via a second routing line in the bending area, and a crack prevention layer disposed on the second routing line in the bending area. Thus, the crack prevention layer is capable of preventing the occurrence of cracks in the bending area BA, thus preventing cracks from spreading to the active area AA.
