Embodiment Construction

[0031] In a flexible display panel, multiple grooves are provided on the side of the pixel defining layer away from the base substrate to increase the contact area between the pixel defining layer and the cathode layer, and increase the distance between the pixel defining layer and the cathode layer. Bonding force to avoid partial peeling when the flexible display panel is impacted or bent.

[0032] However, at the position where the pixel defining layer has grooves, the distance between the cathode layer and the anode is too close, there is a risk of breakdown, and it is easy to cause a short circuit due to particles and the like. In addition, the distance between the cathode layer and the anode If the distance is too close, many large capacitors will be connected in parallel to the device, which will cause abnormalities such as uneven display and affect the display effect.

[0033] Aiming at the problem that the short distance between the cathode layer and the anode in the d...

Abstract

The invention discloses a display panel and a display device. The display panel comprises an underlayment substrate, a driving circuit, a flattening layer, a plurality of anodes, a pixel defining layer and a cathode layer. The flattening layer has a plurality of first grooves in the surface of the side away from the underlayment substrate, and some anodes are located in the first grooves. The pixel defining layer has a plurality of second grooves in a relationship of one-to-one correspondence with the first grooves in the surface of the side away from the underlayment substrate, and part of the cathode layer is located in the second grooves. The orthographic projections of the first grooves and the second grooves on the underlayment substrate at least have overlap areas with the orthographic projections of the anodes on the underlayment substrate. The orthographic projection of each second groove on the underlayment substrate is located within the range of the orthographic projection of the corresponding first groove on the underlayment substrate. In the display panel, the distance between the anodes and the cathode layer is increased. The influence of short distance between the cathode layer and the anodes on the display effect is avoided, and the impact resistance and bending resistance of the display panel are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the continuous development of display technology, more and more display devices are widely used in people's daily life and work. Among them, flexible display panels have the advantages of thinness, foldability, etc., and can be used in various forms and Therefore, flexible display panels are more and more popular. [0003] However, in a flexible display panel, when the distance between the anode and the cathode layer is too short, the display effect is poor. Contents of the invention [0004] Embodiments of the present invention provide a display panel and a display device, which are used to solve the problem in the prior art that the distance between the cathode layer and the anode is too short to affect the display effect. [0005] In a first aspect, an embodiment of the present invention provides a d...
