Abstract
An organic light emitting diode display panel is provided and includes a display region and a through hole configured to receive an electronic element. The display region is disposed around a periphery of the through hole and includes a barrier structure and an encapsulation structure layer covering the barrier structure. The barrier structure is disposed on a side of a periphery of the through hole. The present invention, by extending the encapsulation structure layer from the display region to the barrier structure to cover the barrier structure, prevents water from invading an organic light emitting layer of the display region through the through hole.
