Abstract
The invention provides a display panel and a display device. The display panel comprises a substrate and a pixel definition layer located on one side of the substrate, the pixel definition layer comprises a plurality of pixel openings arranged in an array mode, and the projection of the pixel openings on the substrate comprises a first side edge. The first dimming layer is located on the side, away from the substrate, of the pixel defining layer, the first dimming layer comprises a plurality of dimming openings, and the dimming openings correspond to the pixel openings. The projection of the dimming opening on the substrate comprises a main body part and at least one first protruding part connected with the main body part, and in the projection plane, the first protruding part is at least partially located on the side, away from the center of the dimming opening, of the first side edge. In the preparation process of the display panel, the alignment deviation between the mask plate and the substrate can be partially counteracted by the first protruding part, and finally, after the alignment deviation is generated by the dimming opening of the first dimming layer, the influence of process fluctuation on the lighting effect can be reduced.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic Light Emitting Display (OLED, Organic Light Emitting Display) is used as a light-emitting element in an organic light-emitting display device, which has the characteristics of self-luminescence, does not require an additional light source, is conducive to the overall thinning of the display device, and can realize the production of flexible display screens . In addition, organic self-luminous display technology also has the characteristics of fast response speed and wide viewing angle, which has become the focus of current research. [0003] In the current display panel, as the integration level of the panel becomes higher and higher, the number of film layers above the luminescent material layer gradually increases, and the increase of film layers leads to an increase in light loss between film...
