Abstract
A display panel is discussed. The display panel according to an embodiment includes driver integrated circuits (ICs); data lines disposed in an active region; input pads disposed in a pad region; output pads disposed in a first inspection circuit included in the pad region, the output pads receiving first signals from the input pads; and a first switching circuit disposed in the first inspection circuit and connected to the output pads. The first switching circuit is configured to supply the first signals to the data lines. The display panel further includes first signal lines configured to supply the first signals to the output pads; a second switching circuit disposed in a second inspection circuit and connected to the data lines in the active region; and a second signal line configured to supply second signals to the second switching circuit.
