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.

Abstract: A display device may include a display part, a substrate, a first spacer, a second spacer, a first touch electrode, and a second touch electrode. The display part may emit, transmit, and/or reflect light. The substrate may overlap the display part and may receive a touch. The first spacer and the second spacer may be formed of a spacer material and may be positioned between the display part and the substrate to maintain a distance between the display part and the substrate. No intervening spacer analogous to the first spacer or the second spacer may be positioned between the first spacer and the second spacer. The first touch electrode may be positioned between the first spacer and the second spacer in a plan view of the display device. The second touch electrode may intersect the first touch electrode in the plan view of the display device.
