A display device is provided. The display device includes a first substrate, wherein the first substrate includes: a scan line extending along a first direction; a thin-film transistor, including a source electrode, a drain electrode and a channel region disposed between the source electrode and the drain electrode; a data line intersecting with the scan line and extending along a second direction, wherein the source electrode is a portion of the data line, and the thin-film transistor is coupled to the data line and the scan line; and a touch signal line is disposed above the data line, wherein the touch signal line does not overlap with the channel region; a second substrate; and a display medium disposed between the first substrate and the second substrate.
