Organic Light Emitting Diode Display Panel, Manufacturing Method Thereof, and Display Device

Abstract

An organic light emitting diode display panel, a manufacturing method thereof and a display device are provided, the organic light emitting diode display panel includes: a pixel defining layer, which includes a first opening, a second opening and a pixel defining structure between the first opening and the second opening, the first opening is provided with a light emitting layer and a first electrode which are stacked, the second opening is not provided with the light emitting layer; a first lateral edge of the pixel defining structure adjacent to the first opening forms a first included angle with a plane parallel to a main surface of the base substrate, and a second lateral edge of the pixel defining structure adjacent to the second opening forms a second included angle with a plane parallel to the base substrate, the first included angle is smaller than the second included angle.
