Abstract
An organic light emitting diode (OLED) display panel includes a display device substrate, a cofferdam, a transparent conductive metal layer disposed on the display device substrate, and a light-emitting layer disposed on the transparent conductive metal layer. A cushion layer made of a hydrophilic material is disposed around an active area on the display device substrate, and the cofferdam is disposed on the cushion layer. The transparent conductive metal layer extends obliquely upward toward a direction close to the cushion layer and a periphery of the transparent conductive metal layer is on the cushion layer.
