Abstract: A display device is disclosed that includes a pixel layer, a touch sensing layer, and a sensing pattern. The pixel layer includes first pixel units, each including first sub-light emitting regions, and second pixel units, each including second sub-light emitting regions. The touch sensing layer includes sensing electrodes, and driving electrodes electrically insulated from the sensing electrodes, at least some of the sensing electrodes and the driving electrodes each includes a dummy pattern defining dummy openings overlapping the first sub-light emitting regions when viewed in a plan view, and a sensing pattern electrically insulated from the dummy pattern and spaced apart from the first sub-light emitting regions and the second sub-light emitting regions when viewed in a plan view. The light blocking pattern is disposed on the touch sensing layer, defining light blocking openings overlapping the first sub-light emitting regions when viewed in a plan view, and overlapping the first pixel units when viewed in a plan view.

Abstract: Provided is a display device in which a defect by external light reflection is minimized in a non-display area. The display device includes a display panel and a touch unit arranged on the display panel. The display panel may include: a substrate including a display area and a non-display area arranged around the display area; an insulator including a valley portion, the valley portion being defined as an opening arranged along an outer side of the display area in the non-display area; and a display unit arranged in the display area and including a light-emitting element electrically connected to a thin film transistor. The touch unit may include a reflection prevention unit that overlaps the valley portion and is configured to reduce reflectivity of external light.
