Abstract: Provided is an input detection unit with a plurality of first electrodes and second electrodes insulated from the first electrodes. Dummy patterns are disposed between the patterns and the detection patterns. A secondary dummy pattern is disposed adjacent to the dummy patterns. Signal lines overlap the non-detection area. The signal lines include a first signal line connected to the patterns and a second signal line connected to the detection patterns. The plurality of patterns includes a row of patterns closest to the non-detection area. The secondary dummy pattern overlaps a portion between the row of patterns closest to the non-detection area and the second signal line.

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.
