Abstract: A display device includes a peripheral area around a display area, a display element in the display area, and a dam in the peripheral area. A thin film encapsulation layer covers the dam and the display element. A touch sensor is on the thin film encapsulation layer. A first insulating layer is between the thin film encapsulation layer and the touch sensor and has a first region and a second region. A dielectric constant of the first region is lower than a dielectric constant of the second region, and the first region is between the dam and the touch sensor.
