Abstract: A lighting device includes a substrate including a display area and a non-display area and an organic light emitting layer disposed in the display area. A first electrode is disposed on the organic light emitting layer and a second electrode is disposed below the organic light emitting layer. A phase change material layer is disposed below the second electrode and a plurality of third electrodes is disposed between the substrate and the phase change material layer. Therefore, a pattern having various colors of light and various shapes may be implemented based on a shape of the plurality of third electrodes, a phase change of the phase change material layer, and a color of light emitted from the organic light emitting layer.
