Abstract: A display device includes a first electrode and a second electrode disposed on a substrate and spaced part from each other in a first direction. A light emitting element is disposed between the first electrode and the second electrode. A third electrode is disposed on the first electrode and electrically contacts an end portion of the light emitting element. A fourth electrode is disposed on the second electrode and electrically contacts another end portion of the light emitting element. A side of the third electrode and a side of the first electrode are located on a first virtual line substantially perpendicular to the substrate. A side of the fourth electrode facing the side of the third electrode and the side of the second electrode are located on a second virtual line substantially perpendicular to 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.
