Abstract: A display device includes a display area including multiple pixels and a separator extending around the pixels, and a peripheral area located around the display area and including a scan driver and an electrostatic element part. Each pixel includes a pixel electrode, a light emitting auxiliary layer, and a common electrode. The light-emitting auxiliary layer is disconnected at the separator between neighboring pixels. The electrostatic element unit includes a first voltage line electrically connected to the scan driver, and multiple electrostatic elements electrically connected to the first voltage line. Multiple contact holes overlap the first voltage line located in the electrostatic element unit, and an insulating layer is located in the contact holes.
