Embodiments of the present disclosure are directed to an OLED display panel and a production method. The OLED display panel includes a driving backplate, an anode arranged at a side of the driving backplate, a light-emitting layer disposed at a side of the anode away from the driving backplate, and a cathode arranged at a side of the light-emitting layer away from the anode. The light-emitting layer has different light-emitting angles for the different areas on the light-emitting layer itself. The range of the light-emitting angle of the light-emitting layer is expanded, and the visible angle of the OLED display panel is enhanced as well.
