Abstract
A display panel and a fabrication method for forming the display panel are provided. The fabrication method includes providing a substrate disposed with a light-emitting device, and forming a first inorganic material layer. The fabrication method also includes forming a first inorganic layer by thinning the first inorganic material layer, and forming a second inorganic layer. Moreover, the fabrication method includes forming a third layer. The third layer is disposed in a first region. Further, the fabrication method includes patterning the first inorganic layer and the second inorganic layer by a dry etching using the third layer as a mask, while simultaneously thinning the third layer. The first inorganic layer and the second inorganic layer in the first region are retained to form a first inorganic encapsulation layer and a second inorganic encapsulation layer, respectively. The third layer is thinned to form a third encapsulation layer.
