A display apparatus includes a display panel and a conductive adhesive. The display panel has a plurality of conductive lines and a dielectric layer covering the conductive lines. At least one of the conductive lines has an open defect. The dielectric layer has at least three repair vias, and locations of the repair vias correspond to the open defect. The conductive line having the open defect is exposed by at least parts of the repair vias. The conductive adhesive is disposed corresponding to a location of the open defect and electrically connected to the conductive line having the open defect through the repair vias. A repair method adapted to the display apparatus is also provided.
