摘要： A display panel includes: a substrate including an opening area, a non-display area at least partially surrounding the opening area, and a display area; a plurality of first lines, each of which includes a first bypass portion along the opening area; a plurality of second lines, each of which includes a second bypass portion along the opening area; and a shield layer overlapping at least one first bypass portion. Each of the first lines includes a first or second conductive line in the non-display area. Each of the first and second conductive lines includes the first bypass portion. The first and second conductive lines are alternately arranged and are disposed on different layers. Each of the second lines includes a third conductive line in the non-display area. Each of the third conductive lines includes the second bypass portion, and at least partially overlaps the first or second conductive line.

摘要： A display panel includes an electrostatic protection circuit including a first protection circuit electrically connected between a first signal line and a second signal line. The first protection circuit includes a first transistor connected between the first signal line and the second signal line and including a gate electrode and a lower gate electrode, a first resistor connected between the gate electrode of the first transistor and the second signal line, a first capacitor connected between the gate electrode of the first transistor and the second signal line, and a second capacitor connected between the lower gate electrode of the first transistor and the second signal line. The lower gate electrode of the first transistor receives a reference voltage.
