Abstract
A display panel measures a contact resistance of an adhesive portion to evaluate adhesion quality of an integrated circuit mounted thereon. The display panel includes a plurality of light-emitting elements, a first pad part including a plurality of first effective pads electrically connected to the light-emitting elements, and n (n being a natural number equal to or greater than 2) first measuring pads insulated from the light-emitting elements, a conductive adhesive film on the first pad part and including a plurality of conductive balls, an integrated circuit on the conductive adhesive film, and including an internal line electrically connected to the first measuring pads by the conductive balls, and a second pad part including a plurality of second effective pads electrically connected to the first effective pads, and 2n second measuring pads electrically connected to the first measuring pads.
