A display device is provided. The display device includes a first substrate, a first drain, a planarization layer, a first pixel electrode, a second substrate, and a spacer. The first drain is disposed on the first substrate. The planarization layer is disposed on the first drain and has a first contact hole exposing the first drain. The first pixel electrode is disposed on the planarization layer and is electrically connected to the first drain via the first contact hole. The second substrate is disposed opposite to the first substrate. The spacer is disposed between the planarization layer and the second substrate. The spacer at least partially overlaps with the first contact hole.
