Abstract: The present invention provides an organic light emitting diode display panel and a display device, and relates to the field of display technology, which can solve the problem that the display contrast of an existing organic light emitting diode display panel and an existing display device is reduced due to the reflection of ambient light. In the organic light emitting diode display panel and the display device of the present invention, a light gathering unit and a light absorption layer matched with each other are arranged in pixel defining regions, so that the incident ambient light can be gathered by the light gathering unit to the light absorption layer and absorbed by the light absorption layer, to reduce ambient light outgoing from the display panel due to reflection, and increase the contrast of the display panel.

Abstract: A method of manufacturing a display substrate, a display substrate and a display device are provided. The manufacturing method includes: forming an organic material layer in a display area (10) and a non-display area (11); forming an auxiliary layer (24, 25) in the non-display area (11) before forming the organic material layer. The performances of the auxiliary layer (24, 25) are changed after heating, to allow a portion of the organic material layer corresponding to the auxiliary layer (24, 25) can be easily stripped off. The method further includes removing the portions of the organic material layer corresponding to the auxiliary layer by a heating process.
