Abstract
The present disclosure provides an organic light-emitting diode (OLED) display panel comprising a display area, a non-display, and a block area provided in the non-display area. The OLED display panel includes a signal trace layer, an organic film layer, and an anode layer which are sequentially located on the signal trace layer. The signal trace layer is provided with a signal trace in the non-display area. When an anode is formed on the anode layer, an anode material layer at least covering the exposed signal trace is formed in the corresponding block area, so as prevent mis-etching of the signal trace caused by the etching solution.
