Abstract: The display device may include a first substrate including a plurality of pixel areas; a plurality of display elements arranged in the plurality of pixel areas on the first substrate; a second substrate facing the first substrate; a plurality of spacers arranged between the plurality of pixel areas and maintaining a constant space between the first substrate and the second substrate; and a plurality of touch sensing electrodes arranged on a surface of the second substrate which faces the first substrate. Here, each touch sensing electrode may include at least one first area and at least one second area that is electrically separated from the first area. The plurality of spacers may be arranged to correspond to the first area.
