Abstract
A display panel and a display device are provided. By configuring an auxiliary cathode layer such that a lateral end of a second auxiliary cathode extends beyond a lateral end of the first auxiliary cathode, a full-surface application of light-emitting materials can be realized during the formation of subpixels. This setup facilitates the segmentation of the light-emitting material layer, enabling the formation of light-emitting material sections in the respective subpixels, with cathodes aligned with the light-emitting material sections. This design prevents overlapping of different light-emitting colors that could lead to display anomalies. Accordingly, the display panel operates effectively without the need of using mask plates for forming the subpixels, increasing the pixel density of the display panel. Also, the contact between the cathode and a lateral side of the second auxiliary cathode reduces the impedance of the cathode.
