An organic light-emitting display (OLED) and manufacturing method thereof, and display device; the OLED comprises an anode (2), a hole injection layer (3), a hole transport layer (5), an organic light-emitting layer (6), an electron injection layer (7), an electron transport layer (8) and a cathode (9); and a hole buffer layer (4) is provided between the anode (2) and the hole injection layer (3) or between the hole injection layer (3) and the hole transport layer (5) so as to limit an excess of holes being injected into the organic light-emitting layer (6). A polymer is added between the anode (2) and the hole injection layer (3) or between the hole injection layer (3) and the hole transport layer (5) to serve as the hole buffer layer (4), thus effectively limiting an excess of holes being injected into the organic light-emitting layer (6), realizing a balanced injection of electrons and holes in the organic light-emitting layer (6), effectively reducing the working voltage of the OLED while improving the efficiency and brightness thereof, and further reducing the power consumption thereof. |
