Abstract: A thin and lightweight display device is disclosed. An organic light-emitting display device having a touch sensor is configured such that an outer planarization layer fills a space between a plurality of dams, thereby preventing a short circuit between routing lines in the space between the dams, and such that touch electrodes are disposed on an encapsulation structure for encapsulating a light-emitting element, with the result that an additional bonding process is not required, whereby the process is simplified and cost is reduced.

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.
