Abstract: A display panel includes two or more gate layers including a plurality of gate patterns extending in a first direction and one or more source-drain layers including a plurality of source-drain patterns extending in a second direction crossing the first direction. The gate patterns of the two or more gate layers are curved or bent along a hole surrounding area corresponding to a periphery of a hole in an active area. The source-drain patterns of the one or more source-drain layers are curved or bent along the hole surrounding area. The gate patterns of at least one of the two or more gate layers overlap the source-drain patterns of at least one of the one or more source-drain layers in a thickness direction of the display panel in the hole surrounding area.

Abstract: A display device includes a first substrate, a second substrate, a transistor, a display element, a first touch electrode, a second touch electrode, a spacer, and a light reflector. The second substrate overlaps the first substrate. The transistor is positioned between the first substrate and the second substrate. The display element is electrically connected to the transistor. The first touch electrode contacts the second substrate. The second touch electrode contacts the second substrate and is insulated from the first touch electrode. The spacer overlaps the first touch electrode and is positioned between the first touch electrode and the first substrate. The light reflector overlaps the second touch electrode, is positioned between the second touch electrode and the first substrate, and is spaced from the spacer. A distance between the light reflector and the second touch electrode is greater than a distance between the spacer and the first touch electrode.
