Abstract: Embodiments of the present application provide a display substrate comprising a plurality of first banks distributed in a first direction and a plurality of second banks distributed in a second direction. Two adjacent first banks define a group of sub-pixel units of the display substrate, and two adjacent second banks define one sub-pixel unit. The first bank has a height greater than a height of the second bank. Embodiments of the present application also disclose a manufacturing method of a display substrate and a display device.

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.
