Organic Light Emitting Display Panel

An organic light emitting display panel, wherein comprises:

• a substrate;
• a plurality of anode electrodes arranged on the substrate in an array manner;
• a pixel defining layer arranged on the substrate and at least exposing partially the anode electrode, thereby an effective light emitting area corresponding to each of the anode electrode and a non-effective light emitting area located around the effective light emitting area being defined;
• a blocking pattern arranged on the pixel defining layer and at least surrounding partially the effective light emitting area;
• an organic light emitting layer arranged on the anode electrode, the blocking pattern, and the pixel defining layer;
• a cathode layer arranged on the organic light emitting layer, wherein the blocking pattern separates the organic light emitting layer and the cathode layer in the effective light emitting area, and the organic light emitting layer and the cathode layer in the none-effective light emitting area.
