摘要：
An OLED light emitting device includes a substrate, a thin film transistor, an anode, an organic light emitting layer, a cathode, and a smoothing layer. The smoothing layer is disposed between the organic light emitting layer and the cathode. This improves transmittance of the cathode, and further improves light-emitting performance of the OLEO light emitting device.
