Abstract: An organic light-emitting diode (OLED) element and a display device are provided. The OLED element includes a base substrate and an anode, an organic functional layer and a cathode sequentially stacked on the base substrate. A thermal expansion layer is disposed on at least one of a side of the anode away from the organic functional layer or a side of the cathode away from the organic functional layer and is a transparent thermal expansion layer.
