The invention relates to an organic electroluminescent display panel, which comprises a passivation layer and a pixel electrode; the pixel electrode is formed on the passivation layer; at least one part of the pixel electrode is embedded in the passivation layer. In this way, by embedding part of the pixel electrode in the passivation layer, on the one hand, the stress can be effectively dispersed when the display panel is impacted or bent; on the other hand, the contact area between the pixel electrode and the passivation layer is increased, so that the pixel There is a better bonding force between the electrode and the passivation layer. Compared with the existing design, the adhesion between the film layers depends on the van der Waals force, which improves the adhesion of the electrode. In this way, the breakage or partial peeling of the pixel electrode can be effectively avoided, and the reliability of the OLED display panel's bending resistance and drop impact strength can be effectively improved. A display device is also provided.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescent display panel and a display device. Background technique [0002] In recent years, with the development of society and the advancement of science and technology, the technological development of smart terminal equipment and wearable equipment is changing rapidly, and the requirements for flat panel display are gradually increasing, and the demand is becoming more and more diverse. OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode display device) display device has higher brightness and response speed while having lower power consumption than liquid crystal display, and has the advantages of being bendable and flexible, so it is used It is more and more widely used in smart terminal products such as mobile phones, tablet computers and even TVs, and has become the mainstream display in the display field. [0003] In order to pursue a b...
