Abstract: An organic light emitting display device includes a substrate, an insulation layer structure, a light emitting layer, and an optical module. The substrate has an opening region, a peripheral region surrounding the opening region, and a display region surrounding the peripheral region. An opening is defined through the substrate in the opening region. The insulation layer structure is disposed in the display region and the peripheral region on the substrate. The light emitting layer is disposed on the insulation layer structure, and extends in a first direction from the display region into the opening region. A first opening is defined through the light emitting layer in the peripheral region. The optical module is disposed in the opening of the substrate.

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.
