A display device includes a common substrate having a first surface and an opposite second surface, a first transparent conductive layer, at least one first electrode, and at least one second electrode. The first transparent conductive layer is positioned on the first surface. The at least one first electrode and the at least one second electrode are on the first surface and electrically connected to the first transparent conductive layer. The display device further includes a second transparent conductive layer, a first alignment layer, a liquid crystal layer, a second alignment layer, a thin film transistor panel, and a polarizer all stacked on each other in sequence along a direction from the first surface to the second surface of the common substrate. The second transparent conductive layer is positioned on the second surface of the common substrate.
