Abstract: A display device, a display panel, and a manufacturing method thereof are provided. The method includes: providing a display substrate including a display region having an opening region and an isolation region surrounding the opening region; forming a light-emitting layer covering the overall display region; forming a blocking layer on the light-emitting layer, the orthographic projection thereof on the display substrate covering an overall opening region and at least part of the isolation region; forming a first packaging layer covering the light-emitting layer and the blocking layer; forming a photoresist layer to pattern the first packaging layer and form a first through hole, the orthographic projection of the first through hole on the display substrate being within that of the blocking layer on the display substrate; removing the photoresist layer with stripper; and removing the blocking layer and part of the light-emitting layer corresponding to the first through hole.

Abstract: The present disclosure provides an organic light emitting diode (OLED) substrate and a manufacturing method thereof, and a display device. The OLED substrate includes: a base substrate; a pixel defining layer on the base substrate, the pixel defining layer including pixel defining patterns for defining sub-pixel units, each sub-pixel unit being defined between adjacent two of the pixel defining patterns; and an organic light emitting layer on a side of the pixel defining layer away from the base substrate, the organic light emitting layer including a first portion in each sub-pixel unit and a second portion on each pixel defining pattern. Each pixel defining pattern is provided with a groove structure therein, and part of the second portion of the organic light emitting layer in the groove structure and the other part of the second portion of the organic light emitting layer are spaced apart from each other.
