The OLED display panel provided by the embodiment of the present invention includes an array layer, the array layer includes a TFT device, and a passivation layer disposed above the TFT device, the passivation layer includes a first passivation layer and a second passivation layer, and the second passivation layer The water and oxygen blocking ability of the layer is greater than that of the first passivation layer; by setting the passivation layer into a two-layer structure, one of the layers plays a good role in blocking water and oxygen, which relieves the upper part of the passivation layer and the outside world. The effect of water and oxygen changes on TFT devices. |
