Abstract
Provided is an organic light emitting diode display panel, including a substrate, a thin film transistor array layer and an organic light emitting diode layer, which are sequentially stacked and disposed on the substrate, and a thin film encapsulation layer covering the organic light emitting diode layer and an inorganic barrier layer disposed on an outer periphery of the thin film encapsulation layer, wherein at least two grooves in circle around a periphery of the organic light emitting diode layer are provided in the non-display area on the thin film transistor array layer, and the at least two grooves are correspondingly disposed to the thin film encapsulation layer, and the thin film encapsulation layer completely covers the organic light emitting diode layer, and fills the grooves corresponding to the thin film encapsulation layer. The OLED display panel possesses a dense and stable package structure.
