Abstract: The present disclosure provides an OLED display panel, a manufacturing method thereof and a mask plate. The OLED display panel includes an emitting layer and a cathode located at a light-exiting side of the emitting layer. The cathode is provided with gaps. Light emitted from the emitting layer may directly transmit through positions corresponding to the gaps, and then the cathode may have a decreased absorption and reflection against light emitted from the emitting layer as comparing with a cathode formed as a whole layer in the related art, thereby improving the light extracting rate of the OLED display panel, weakening the micro-cavity effect and solving the problem that the display color of the OLED display panel changes with different viewing angles.
