Abstract
Disclosed herein is an OLED lighting apparatus which can achieve both improvement in reliability and reduction in manufacturing cost. In the OLED lighting apparatus, an encapsulation layer is disposed over the active area and the non-active area on a buffer layer, such that a pad disposed in the non-active area of the buffer layer can be stably secured by the encapsulation layer bonded thereto. Accordingly, upon tape automated bonding between an FPCB substrate with a COF tape attached thereto and a via electrode, the COF tape does not directly contact the pad but contacts the via electrode connected to the pad, particularly a connection terminal of the via electrode disposed on an upper surface of the encapsulation layer, thereby establishing electrical connection between the FPCB substrate and the via electrode. In this way, the connection terminal of the via electrode is electrically connected to the FPCB substrate via the COF tape, whereby a signal from the outside can be applied to the pad connected to the via electrode.
