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.
