Abstract: An electroluminescence display apparatus includes a substrate including a display area and a non-display area. The non-display area includes a bending area and a link area. A first power supply electrode is in the link area. A second power supply electrode is in the non-display area. The second power supply electrode surrounds at least three sides of the display area, and both ends of the second power supply electrode in the link area. A protective layer covers the first power supply electrode and the second power supply electrode in the link area. A first planarizing layer covers one side of the first power supply electrode; and a second planarizing layer is on a contact hole of the protective layer that exposes the first power supply electrode and the second power supply electrode. The first planarizing layer is not on the contact hole.
