Abstract: Provided is a display device comprising a display panel including a display area and a non-display area and an electrostatic protection circuit disposed in the non-display area. The electrostatic protection circuit includes a first stage circuit including a (1-1)-th diode which causes a forward current to flow from a first node to a second node and a first capacitor and a first resistor connected in parallel to the (1-1)-th diode, a second stage circuit including a (2-1)-th diode which causes a forward current to flow from the second node to a third node and a second capacitor and a second resistor connected in parallel to the (2-1)-th diode, and a third stage circuit including a (3-1)-th diode which causes a forward current to flow from the third node to a fourth node and a third capacitor and a third resistor connected in parallel to the (3-1)-th diode.

Abstract: A display device includes a first substrate and a second substrate opposing each other. One of the first and second substrates includes a display surface. The display device further includes a display area and a non-display area surrounding the display area when viewed in a direction perpendicular to the display device. The display device includes a common voltage line formed in the non-display area and over the first substrate, at least one column spacer formed over the common voltage line, a conductive layer formed over the first substrate to cover the column spacer and electrically connected to the common voltage line, a common electrode formed over the second substrate and electrically connected to the conductive layer, and a liquid crystal layer interposed between the first substrate and the second substrate.
