Abstract
An organic light-emitting diode (OLED) display panel and a method of fabricating the OLED display panel are provided. By providing a gap between a first electrode and an inner wall of the first opening, an organic light-emitting material will only flow into the gap between the first electrode and the inner wall of the first opening through the first opening. In this way, it is difficult for the organic light-emitting material to be sputtered on a contact surface between the first electrode and a cathode, so that display uniformity is enhanced.
