Abstract

The invention discloses a display panel, a manufacturing method of the display panel and a display device. The display panel comprises a base plate, a pixel defining layer and a first electrode, wherein the pixel defining layer is positioned on the base plate and comprises a plurality of openings and separation levees; each separation levee is surrounded at each opening and comprises a top surface, a bottom surface and at least one side surface; the side surface connects the top surface and the bottom surface; the area of the top surface is greater than the area of the bottom surface; the at least one side surface comprises a notch; the first electrode is positioned at the bottom of each opening and extends to the notch; relative to the base plate, the height of the first electrode is smaller than or equal to the maximum height of the notch. The height of the first electrode is smaller or equal to the maximum height of the notch relative to the surface of the base plate, so that the first electrode cannot climb to the upper part of the separation levee; the electric leakage risk is reduced.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In existing organic electroluminescent devices, the pixel defining layer generally has a roughly trapezoidal shape, and the width of the upper part is smaller than that of the lower part. The wall and the upper part will cause a short circuit between the anode and the cathode, or cause the risk of leakage, thereby affecting the display effect of the organic electroluminescent device. Contents of the invention [0003] Embodiments of the present disclosure provide a display panel and a manufacturing method thereof, which can at least solve at least one of the above problems. [0004] The first aspect of the present disclosure provides a display panel. The display panel comprises: a substrate; a pixel defining layer located on the substrate, the pixe...
