AI Technical Summary
Technical Problem
Existing display products suffer from a serious problem of excessive brightness, resulting in poor display quality.
Method used
By setting a first pixel limiting structure and a second pixel limiting structure in the display panel, the position and opening of the light-emitting element are limited, and the undercut structure is used to block the lateral leakage between adjacent light-emitting elements, thereby improving the display effect.
Benefits of technology
It achieves better light output effect from a wide viewing angle and reduces lateral leakage, thus improving the display effect of the display panel.

Abstract
The embodiment of the invention discloses a display panel and a display device. The display panel comprises a driving substrate, a plurality of light-emitting elements, a first pixel limiting structure and a second pixel limiting structure. The plurality of light-emitting elements are located on one side of the driving substrate. The first pixel limiting structure is located on one side of the driving substrate, the first pixel limiting structure comprises a pixel opening branch part and a pixel limiting branch part, the light-emitting element is located in the pixel opening branch part, and the pixel limiting branch part surrounds at least part of the light-emitting element. The second pixel limiting structure surrounds at least part of the light-emitting element, and one side, facing the light-emitting element, of the second pixel limiting structure is provided with an undercut structure. Thus, the positions of the light-emitting elements and the sizes of the openings are limited through the first pixel limiting structures so that a good large-viewing-angle light emitting effect can be achieved, and the adjacent light-emitting elements are separated through the second pixel limiting structures so that transverse leakage current can be reduced.
