Abstract
The present disclosure provides an organic light emitting diode (OLED) display panel and a method for manufacturing same. The OLED display panel includes a substrate, a thermal insulating layer, a buffer, a driving TFT, and a storage capacitor. The substrate includes an arrangement area. The thermal insulating layer is disposed in the arrangement area. The buffer layer is disposed on the substrate. Both the driving TFT and the storage capacitor are disposed on the buffer layer to correspond to the arrangement area. According to the present disclosure, the thermal insulating layer prevents heat in the amorphous silicon layer from dissipating rapidly when an annealing treatment is performed for the amorphous silicon layer to have amorphous silicon crystallize.
